Sammamish City Directory Sources
No official source reviewed publishes a complete, searchable run made solely for Sammamish. That gap shapes the sound way to research the area. Start with the collection that fits the date and the place label used then. A Seattle volume can be a regional lead, but it is not proof that a Sammamish-area address fell within Seattle. Likewise, a photograph caption or oral history can point to a name without proving residence.
| Collection | Years or scope | Where held | Access |
|---|---|---|---|
| Seattle city directories | Digitized 1867 to 1928; research-room volumes 1890 to 1990 | Seattle City Archives | Online referral or research room; only when the old jurisdiction fits |
| Federal census schedules | Public individual schedules through 1950 | National Archives | Online and archive help under the 72-year rule |
| Washington historical series | Census, school, land, vital, court, photo, and oral-history series | Washington Digital Archives | Free search; index, image, or catalog lead |
| King County Collects | Material from 61 institutions | UW Libraries platform | Cross-collection search; item access varies |
| Sammamish Heritage Society | Local preservation since 1999 | Society contact route | Inquiry; no public person-name index located |
| KCLS Sammamish | Local branch milestones since 1994 | Sammamish Library | Catalog, staff referral, scanning, printing, fax, computers |
No verified Sammamish-specific directory run, complete local obituary index, or local newspaper-name database appeared on the official KCLS page. Ask for an exact catalog search rather than assuming a shelf exists.
Sammamish Directory Place Names
Before incorporation on August 31, 1999, the plateau was unincorporated and tied in different ways to Redmond and Issaquah. Historic sources may use Inglewood, Monohon, Weber Point, Beaver Lake, Pine Lake, Lake Sammamish, Klahanie, Sahalee, Trossachs, Providence Point, or simply Plateau. A rural route, school district, township, range, or postal city may be the only label that links one record to the next.
Use the modern and historic name in parallel. For a Beaver Lake lead, test Beaver Lake Colony, lake resort, school, township and range, and King County. For Inglewood, try Inglewood, Monohon, Lake Sammamish, Redmond, and rural-route variants. Keep the spelling from each source even when it looks old or inconsistent.
Note: A negative result under Sammamish may show a place-name mismatch, not the absence of a historical record.
Read a Sammamish Directory Entry
A city directory entry must be read on its own terms. Regional directories may arrange people by surname, business, or street. Later reverse sections can arrange listings by address. Always save the volume title, year, publisher, page, and abbreviation key. Do not expand a mark from memory, since symbols can change between editions.
| Name or subject | Copy the full printed form, initials, spouse notation, and alternate spelling. |
|---|---|
| Role | Record the occupation, firm, householder label, or other role exactly as printed. |
| Address | Preserve the number, road spelling, rural route, postal city, and unit. |
| Edition evidence | Save the title, date, publisher, page, and image or call number. |
| Follow-up | Compare the name and place with a census, deed, archive item, or original city record. |
No sample Sammamish-specific printed entry was located in the official sources reviewed. This inventory is a capture method, not a claim about fields in a local volume. A Digital Archives result needs its series, repository, item title, date, place label, named people, rights note, and image or transcript status saved separately.
- Criss-cross directory
- A later section arranged by street and house number instead of surname.
- Householder index
- A list keyed to the person identified as heading a household, under that publisher's rules.
- Abbreviation key
- The edition legend for short forms and marks; copy it before interpreting an entry.
- Catalog entry
- A description of a held item, which may require a request or visit.
Sammamish Library Directory Access
The Sammamish Library at 825 228th Ave SE is a practical access point. Its page lists public computers, printing, fax, scanning, Wi-Fi, and staff help. The phone is 425-392-3130. Hours observed were Monday 10 to 6, Tuesday and Wednesday noon to 8, Thursday and Friday 10 to 6, and Saturday and Sunday 11 to 6. Check the live schedule because construction, holidays, and service notices can alter it.
The branch history supplies useful date markers: a shopping-center station in 1994, the first library in 1998, KCLS annexation in 2000, and the Sammamish Commons building opening January 9, 2010. Those shifts can affect the catalog, agency, or building name found in a dated source.
The manifest capture of the KCLS location page shows the starting point for current hours and services.

Use the live page to plan a catalog check, then ask staff about old place names and the exact format of each item found.
Search Sammamish Digital Collections
Washington Digital Archives is broader than a city directory. Its inspected branches include census, cemetery, school registers, land, plats, marriage, death, court, corporation, photos, oral histories, and publications. Pick the series first. Then test a surname, road, lake, school, club, farm, or former place name. A result may be an index, scan, or finding aid for material held elsewhere.
The King County Collects search reaches 61 historical societies, museums, and libraries, including the Sammamish Heritage Society. Search captions and titles. A road, resort, school, or family name may appear in a photo caption when there is no structured person field.
The manifest image from King County Collects records this cross-institutional search surface.

A useful hit still needs item-level facts: institution, date, subject, place, media type, provenance, and catalog link.
Sammamish and Regional Directories
The Seattle City Archives describes digitized Seattle city directories from 1867 through 1928 and research-room directories from 1890 through 1990. Such books can list residents and firms by name and address, with some occupation, spouse, ownership, or marital clues. Reverse-by-address use is described for later practice, beginning in 1938.
These are Seattle records. They enter Sammamish research only when the person, firm, route, or jurisdiction supplies a sound regional link. The modern line must not be cast back onto an old entry. The right conclusion may be that the volume does not cover the plateau address.
The captured Seattle Archives referral page documents that limited route.

Save the collection scope with every result so a Seattle listing is not misread as proof of Sammamish residence.
Sammamish Heritage Directory Leads
The Sammamish Heritage Society formed in 1999 to discover, document, and preserve local history. Its work includes artifacts, oral histories, talks, interactive projects, and links among people and places. Its first meeting took place in April 1999 at the Paula Lillevand Cottage in Beaver Lake Colony, just months before incorporation.
That story makes Beaver Lake Colony a search term and a repository clue. Contact the society at sammamish.heritage@hotmail.com or 704 228th Ave NE PMB 222, Sammamish, WA 98074. Ask about a surname, dated place, road, photo, or oral-history subject. No searchable person index, transcript inventory, full artifact catalog, or fee schedule was found.
Sammamish Directory Date Markers
A short timeline helps choose the right custodian and label. It prevents a request to the modern city for an old rural county record.
| 1877 | HistoryLink associates permanent non-Indian settlement with Martin Monohon. |
|---|---|
| 1994 | A KCLS station opened in a shopping center. |
| 1998 | The first local library opened. |
| April 1999 | The Heritage Society first met at Beaver Lake Colony. |
| August 31, 1999 | Sammamish incorporated. |
| 2000 | The library annexed to KCLS. |
| January 2010 | The Commons branch opened. |
| January 1, 2016 | Klahanie annexation became effective. |
A find before 1999 usually sends the search to King County, an archive, a historic label, or a census. A later civic name may appear in city packets, but it is tied to one event and is not a resident roll.
Trace a Sammamish Household
Use city directories as one rung in an evidence ladder. Begin with the most precise dated source, retain the old spelling, and keep each role separate. A directory listing, taxpayer, deed party, photo subject, and census household member are not the same fact.
- Define the person, date window, road or place, and likely jurisdiction. Save all name forms.
- Search the right regional volume or archive catalog. Copy the edition, page, marks, and address without modernizing them.
- Search the 1900 through 1950 federal census years that fit. Later individual schedules remain closed under the 72-year rule.
- Use the Digital Archives and King County Collects for school, cemetery, land, photo, publication, or oral-history leads.
- Confirm the address or family link with an original census image, deed, plat, certificate, or other official record.
If the trail reaches a modern property question, the Sammamish street directory explains the address route. For a gap, contact Puget Sound Regional Archives or use Ask Archivist. State what was searched and not located.
