Eudocia, Rose and Bessie VanLeuven, who's stones had no surnames and the old 1930's transcription listed their last name as VanLeuven. VanLeuven is the family next to their graves and a conclusion (assumption) was made that the three females were VanLeuvens. Burial records show the last name on the plot is Sibley and their probable parents are George and Eudocia who are buried across the isle from them.
I have also found the 1900 census listing for the VanLeuven family and they had three children and none of their names were Eudocia, Rose or Bessie. The 1900 census shows after the mother's listing that she had 3 children and all were living. This further confirmed that the three females do not belong in the VanLeuven family. The 1880 census was consulted for George and his wife but there were no children listed as of yet in their household. Next I will consult the death records to confirm that George and Eudocia are the girl's parents.
There were other records that had a ? in dates and ages on the older stones because they weren't readable, but the burial records contained them so they have been changed here.
