Gail, I am researching this family for a friend of my mother's who is just starting to get into genealogy. Could you please send me more information on your grandfather's family, including whatever you know on his sister. If the family was in South Dakota in the 1850's, I'm sure we have a match. I'm hoping go visit the LDS Family History Center here in Los Angeles tomorrow to look at Census Records for that time period. Is there anything more you can tell me about Wilhelmina? Mother's name, father's name, siblings, etc. Thanks so much! Cindy Courtier
