The 1889
Washington State and Territorial Census has a
"Wm C. Pierson" age 37 (1852/1853) in
Missouri. He was living in
Kittitas County, he was married and a laborer. The date of enumeration wasn't identified on the page.
The 1900 Census for Cle Elum,
Kitsap county, WA
William C. Pearson, born April 1852, single, born in
Missouri to father born in
New York, mother in
North Carolina.
I looked in the whole State of
Washington for ANY Pierson/Pearson/Pearsen/Piersen born plus/minus 10 years of 1855. That would find anyone born between 1845 and 1865. If he was born before 1845 and left in the 1880's, he would have been elderly by the 1920's/1940's.
The 1930 census had NO
Pearson, a
Gus Pierson from Sweden.
For this person to have a "
Pierson and sons", he probably would have had to have sons, probably would be listed with sons in the 1900/1930 Census. UNLESS, he married a woman after 1930 that had sons, but that doesn't sound credible if he was born in the 1850/1860 time frame.
IF your ggaunt did witness a family member with
Pierson and sons, it "might" have been a son of this William Pierson; but unless your William
Pierson skipped out on this one also, nothing to be found of a possible son in the census.
Without more information, his
DOB, or even State of his birth, who his parents were, so he can be found in
Arkansas in the 1870 or 1880 census. That would give us the approximate age. Is your ggaunt part of a family that contains a
Pierson?
I worked a case a few months ago where the family member was POSITIVE they visited someone in a certain place. But, I found them in another place, they had been there for years before and after. So, the mind plays tricks after a while. Your ggaunt was probably in her teens during the time period? Okanogan might have been a memory because of something else, the great Indian Reservations, etc. OR, maybe someone did go into a
Pierson and Son's grocery and William was discussed at the time; but he wasn't actually found there.
But, until the
Pierson and Son's Grocery is found, we can't speculate. Hard proof is needed. Start with Okanogan, also look at Kitsap and Kittitas Counties.
