Hi Cathie - You have the right David & Charlotte for Annie's parents, an the right parents for David. Charlotte's nee name Burnham.
The 1860 census is the only place the name Georginna shows up, and I too, have figured that she could be Annie b.c1860 Michigan, unless Annie was born just after this census was writen, and the girl Georginna b. 1859 died as a child.
I have 3 children for Annie & Samuel, who do you decend from?
