I am a descendant of Rensselaer Lamb. My line of descent is through Lucy's brother , Rensselaer Lealdus Lamb. Lealdus, and brothers, Silas A. and William Henry Harrison Lamb, also moved to Kansas in the 1870's. When their father died in Ellicottville, New York in 187l, his will mentions that Lucy Razey is living in Carthage, Jasper Co., Missouri. (The spelling of Razey is how it was spelled in the will.) I do have lots of information on the Renssealer line. Lealdus's son Renssealer John Lamb eventually moved to Texas and that is where I live . I will be happy to share a hard copy of my research with you.
