I am looking for information on the William M.Calkins family found in 1920-1930 census of Bennett County. Wife Francis aka Fannie S, b. C1880, Bohemia; daughters Helen V. b. C1906 & Francis M. b. C 1909, both b. in NE. William is found in 1900 census of Cherry Co. NE with his brother,Addison, and father, Ebineezer (Ebenezer).

Not sure what kind of information you are looking for. The South Dakota State Archives has a searchable database of cemetery records - http://apps.sd.gov/applications/DT58Cemetery/
There are several Calkins listed in this database, including:

Fannie S. Calkins
Death date: 02-01-1963
Lot: 2
City: Martin
County: Bennett
Cemetery: Our Lady of Sacred Heart

William Calkins
Death date: 1949
Lot: 3
City: Martin
County: Bennett
Cemetery: Our Lady of Sacred Heart

"This searchable database includes records that were cataloged as part of the WPA Cemetery Project (pre-1940s) plus any cemetery updates that our office has received. It is not a complete listing of all the burials in South Dakota."

I guess I am looking for any information at all. This is one of my "grasping at straws" queries. William Calkins' mother was a sister to my husband's ancestor, Abigail Brown, who is one of my serious dead ends. I am hoping I can find some sliver of a clue that will help me to locate information for his mother. I know from census records that he was b. in NE, but cannot locate him with his family there. I appreciate your reply and will try to persue further information from death records or an obit.

thank you so much for your reply
