I didn't look at your other postings (124) so I don't know what additional information you may have on this family, but youre question asks for a LOT of research, specifically on each of the family members.

Starting with the immediate family of William and Sarah. Have you researched the US Census 1880, 1900/1910/1920/1930 for each person. Have you researched the Washington Birth and Death Indices, other county records? It appears you have done so, as you have dates in the 1900's, up to 1975. You appear to have a lot of information after the 1850/1870 time period, so that a researcher would be doing a lot of background that you already have.

If you have access to Ancestry.com, there are family trees also available. You can either subscribe or visit your local library for access. Most help on Rootsweb comes from volunteer researchers such as myself, versus a remote family member finding your posting.

If you could be specific as to a family member/brick wall, that might lessen the impact.
