Under "Arthur Martin" in the census...it shows he was born in Indiana...so was his mother...so was his father.("Ind-Ind-Ind").
William Middleton was born, and his parents (according to the census info that Nancy sent) were all born in Illinois. ("Ill-Ill-Ill").
I really think that this whole thing might end up as...William Martin and Anna Martin divorcing three years prior to the census...
When in Salt Lake, I found this for the 1920 census (I have no clue in the world if he might be Arthur's father or not...) _____________________
WILLIAM MARTIN - 56 years old -Gibson County/ Columbiana Township/ City of Oakland (422 Walnut St.)... Ind/ Ind/ Ind
ANNA -46 years old - Ind/ Ind/ Ind
NATHAN - (father)-87 years old - widowed - Ind/ NC/ NC _____________________
Who's father is Nathan ??
But anyway...M-A-Y-B-E (could be)...maybe this is Arthur Edward Martin's biological father who remarried...another "Anna"...???Good Lord...even thinking about all of this is giving me a headache !!(hahahaha !!)
