Shelia: I heard that they're two ways of spelling Burkhart or Burkhardt. My grandmother's second husband is an Burkhardt andher younger sister married an Burkhart. And she is the one that told her daughter about the Blackfoot. Now the Horton is on the other side of the family , going back on my father's side of the family. I don't know very very much on his father's side, but it's hard rearching these lines. I will some day find them, but I have found some info , like on the 1910 Federal Census - Platte City-Smithville District,Clay Co., Mo.There's my ggrandfather Frank Wood,wife Mary S., grandfather Benjamin H. and Ruth M. Horton .I havn't found much since, but I have found that the Horton's are in Mary's line. Still looking.
