Not sure if you're still working on this line.I've sort of figured out that Nelson Alexander came from Kentucky (birthplace he shows on the 1850 census.)He arrived in Illinois very early and may have married his first wife, Margaret Nix before arriving. Her parents (John Mise Nix and Winnifred) and brothers lived nearby in Madison Co. having come from SC in 1813.Nelson's first wife died after the 4th child and in 1829 he remarried to Rachel Smith. Then sometime before 1840 he moved across the river settling in Pulaski Co., MO and died there in 1855.The courts settled his estate, so it may be that he left no will and his wife pre-deceased him.

May 31, 1855 - "Ordered by the County Court that the Public Administration take into hand the Estate belonging to Nelson Alexander, Deceased."
1860 Census for Pulaski Co., MO - there are no Alexander here at all.There would have been minor children and the courts would have had to appoint guardians. Some of the children's marriages found in Phelps Co. but no Alexander on 1860 census there either. Do you know where they were?
