We too were from Baltimore,Maryland. Sarah E.Kilman was born Dec 11,1855 in Annapolis, Maryland but was living in Baltimore in 1870, with her uncle George C. McGuire. Later Sarah married Col. Salome Marsh of Baltimore in 1877. Their daughter Sarah Kilman Marsh my grandmother and fathers mother was born June 25,1889.The other records I believe to be related were from Annapolis. In 1850 N.Kilman 56, S.Kilman 50, H.Kilman 25. Also 1850 Nicholas Killman 41, Sarah Killman 38, William Killman 17, Richard (R.D.G.Killman)15, Mary E.Killman 13, Julia Killman 10, George M.Killman 8, James H.Killman 6. In this same house was William P.Kilman 15, and John M.Kilman 3. In 1860 this same family is listed with one more addition Henry Killman 8. Do you think your William H. could have been called Henry for his middle name because of the other two Williams already, He would have been born in 1851 !?
