I've recently run across a family history that says my grandmother Marie (dad's mom) was a Doty. The information gives 18 April 1915 as her DOB, location Chicago (though this may be date/location of placement--not sure). When I was a child I'd heard she'd been adopted, but not much more than that.
The note I have here says "Marie Dorothy Grau was never legally adopted by Peter and Martha Grau. They raised her and when she was 18 years old she took their name legally. Her birth name was Doty."
So now I wonder where among the Dotys my grandma (and I!) might fit in. Can anyone provide me with some clues in this regard? Many thanks.
