Thanks to all for replies, just working my way through them.
One thing I noted is the death of Marshall Anthony Pearson in 1978, Oregon. This seems to tie him in with an Esther Pearson whereas I have Marshall in the 1930 census living anacortes with wife Marie A (who I believe to be Marie A O#Malley) and son Jack; and in 1940 wife wife Marie A and 4 children living San Francisco. Perhaps somebody could clarify this?
So far I haven't been able to find the marriages of:-
Edward J Pearson and Ada L E Herrle (abt 1937)
Nell Miriam Pearson and .....Zurcher
Marie Allatt Pearson and John E Archbold
I am unable to see the obituary for John E Archbold (
https://familysearch.org/ark:/61903/1:1:QVPT-JM9Q) as I do not have a subscription for the site (GenealogyBank.com.)
So far I haven't found the following in the 1940 census:-
Marie Allatt Archbold (Pearson) and John E Archbold
Nell Miriam Zurcher (Pearson)
Again thanks to all for all your help.
Bob
