MY maternal grandfather, David Henry CROOK b/1/1888 in Spencer Cty In, was the son of SARAH LYDIA LANMAN and Lafayette CROOK. Some of Sarah's siblings are Frank, Rhoda, Johnathan and Constine.there may be others,but these are all that I know about. Neither do I know who Sarah's parents were. I am searching for her parentsother siblings,and the descendants of the siblings that I know of. Can anyone enlighten me??
