I apologize for the other posting.I spent the additional few minutes to look at the cemetery transcriptions, there weren't list.As you may know, cemetery transcriptions are incomplete.Even those that have been transcribed have many unnamed, unreadible stones, etc.Sometimes you're lucky, sometimes you're not.But, before someone gives you a link, it should be check as to not waste your time.
The adopted children could "possibly" be children of a sibling to Ardelia.
Based on your posting, you may have the Census reports already and may also have:
Edward J. Paxton, died 28 January 1941, Cowlitz County, WA., born about 1867 Ardelia J. Paxton, died 10 July 1948 in Longview, Cowlitz, Co, born about 1872,Death Certificate 11353 George G. Paxton, died 22 Feb 1945 in Longview, born about 1896.Certificate 27. --Others "possibly" related: Emma J. Paxton, died 31 May 1944 in Longview, age 73 Sharron F. Paxton, died 28 Feb 1948, died at age 2 in Longview, WA. Virginia L. Paxton, died 10 July 1940 in Cowlitz Co.
I would first try for "possible" obituaries, try the free service from the Washington State Library: The Washington State Library has a free research service, the ask-a-librarian program, where they will look for information in the archives, in this case the newspaper microfilm for an event, such as an obituary.They will look up to an hour and send you the results.Contact them at: http://www.secstate.wa.gov/library/ask.aspxhttp://www.secstate.wa.gov/library/ask.aspx .Depending on the amount of requests, it could take up to a couple of weeks. --As you may know, the further back in time, the less chances for finding an obit as they just weren't done back then.But, give that a try first.
Now, with that, you need someone in the local area to do public records research for you, not someone sending you links from Wenatchee.Try the volunteers at Random Acts of Genealogical Kindness in Cowlitz Co.The link is set for that County: http://www.raogk.com/washingt.htmhttp://www.raogk.com/washingt.htm
