Willis Lamb's family moved from Surry Co. NC to Jackson and Madison Co.. AL in the 18 teens. They first lived in the area of Paint Rock River. Their mother is identified in a letter written by one of Willis' nephews as Martha, but the father's name was not given. One researcher who had died before I learned of this family had told someone that he had found that the father was the older Jacob Lamb who died in Limestone Co. in the 1820s.
Willis was in the 1830 census of both Jackson and Madison Counties. He must have been close enough to the border that he was counted twice or he moved from one county to the other in time to be counted twice. He was living next door to a widow named Pennington. Two of his brothers married daughters of Isaac Pennington's daughter Mary and her husband John Graham (written Grimes in some documents).
The Grahams also came to Jackson Co. AL. Some in this Graham family claim their family tradition has it that Isaac's first wife was a Mary Lamb.
It seems, from the 1830 census that Willis may have been married before 1830, but by 1832 he had moved to Monroe Co. IN where he married Joseph Pennington's daughter Sarah Pennington on 3 May 1832. 
At the time of the 1860 Census, William, his wife Sarah, and three of their children -- Sarah, Louisa and Isaiah -- are all living in Porter Township, Christian County, Missouri. William's mother, Martha (age 98), is also living with them.
