Taylor links Sure! I can link them. Do you happen to have any evidence that Madison was John and Susannah's son other than the 1850 census listing? I've been hoping to firm up that relationship a little because its always possible he could be a cousin or other relative living with them.
Emma Davidson On the 1880 census for Union County my GGrandparents (John and Catherine Davidson) are living next door to Emma and Robert Davidson. Since they are the only two Davidson families in the area I am pretty sure there is a connection but I have not been able to prove it. Do you know anything about Emma's parents?
Gilpan No, it is spelled correctly on the gravestone and on the Find a Grave memorial. It is her husband's and daughter's memorials where the name is spelled incorrectly as Gilpin, and I can't fix them because they aren't my memorials. But you can contact the person who created them and asked them to fix those memorials.
