Well, I don't really have any information on Samuel yet. I think he is somehow connected to my Frederick Connick, but I'm not sure how. I did just find a cemetery listing for Mary and Samuel. Samuel died 19 June 1896 @ age 77 and Mary died Mar 1891. They are buried in Hewitt Cemetery in Red Oak. I got that off the IA Genweb.
Frederick Connick married Sarah Warren in about 1876. At least two of their children were born in Red Oak. The children I know about are Oscar, Winnie (my great grandmother), Rolly, and Ransome. Does any of this connect with you? I believe that Samuel and Frederick are somehow related, because on the 1885 Iowa State Census Samuel and Mary Connick as well as Charles and Della (not sure) Connick are listed on the same page as Daniel and Fidelia Horn. I know that Fidelia Horn is the sister of my Frederick Connick. I know that's pretty confusing so write me if you want clarification.
