I am looking for the John and Catherine Lusk Family. They were living in Des Moines County, Iowa in the 1850's. They are the parents to Sarah E.Lusk,b.1/13/1847, in Iowa, who married Elijah Lines. I would love to find Catherine's maiden name. There were children born to this family including: William B.E. Lusk, b. 1840, Indiana; Hamilton Marion Lusk; Albert S. Lusk, b. 3/20/1844 in Iowa and Sarah E. Lusk, b. 1/13/1847 In Iowa.I have found the cemetery that John Lusk and possibly Catherine are buried in.The stone does not have a death date for Catherine.John died 4/15/1857 in Des Moines County, Iowa.Would be willing to share information.
