No worries, others make the same error. With her birth and marriage so recent in terms of genealogy databases, I still recommend ZabaSearch or BeenVerified. BV will have other names associated the one you search. Search all the names and do it with the state and without. You will at least get cities and you then can do online phone book searches for those cities. I use the free searches and just doing an internet search of name looking for Face Book, MySpace and other postings they may make to social media. Believe it or not you can find condolence messages left on Funeral Homes websites. Look for the children to contact for mother's whereabouts.
