Hi Leon, Thanks for the query and contact! As Host of the ELDER DNA project, I'm always watching for more ELDER connections.
Today I found the 1920 OK census (with date and location problems), and searching the GEORGE HAUN name in Ancestry Family Trees, I found some ELDER clues. Lots of ELDER names in early Indiana. I have research notes for an ELDER group coming from Bedford PA to OH to IN. at http://freepages.genealogy.rootsweb.ancestry.com/~nancyelder/ed/MartinMorrowCoOH.htmhttp://freepages.genealogy.rootsweb.ancestry.com/~nancyelder/ed/MartinMorrowCoOH.htm **** 1920 Ancestry Census for Oklahoma Name:Annie Mcgowen Home in 1920:Calumet, Canadian, Oklahoma Age:73 Estimated Birth Year:abt 1847 Birthplace:Missouri Relation to Head of House:Wife Spouse's Name:Sheridan W Mcgowen Father's Birth Place:Missouri Mother's Birth Place:Missouri Marital Status:Married Race:White Sex:Female Able to read:Yes Able to Write:No Household Members: NameAge Sheridan W Mcgowen78 Annie Mcgowen73 George Haun44(stepson, divorced, laborer) 1876 MO MO MO Source Citation: Year: 1920; Census Place: Calumet, Canadian, Oklahoma; Roll: T625_1455; Page: 8B; Enumeration District: 82; Image: 579. *** Searching Ancestry for "George Haun b. 1876 MO MO MO" found Ancestry Family Tree by Wespeck (Wesley Elliott Peck Family Tree) at http://trees.ancestry.com/tree/5500939/person?ln=elder&fn=http://trees.ancestry.com/tree/5500939/person?ln=elder&fn= for George's Mother: Elkania Haun --Birth abt 1846 in IL, USA
