I see you've posted only 55 messages on Rootsweb. It is helpful to identify the date of birth of the person you seek (In his case also her husbands name). BUT, Your family tree shows Pearl Jensen and her 2007 obit. It identifies the names you posted.
I'd suggest running those names on www.zabasearch.com
to search for them. I found Karen immediately and you only need one to find the others, give her a call. Genealogy sometimes is nothing but common sense. If you want to find someone and you know where they live, use a phone finder online, or call 1-(their area code for that town)-555-1212.
