I and my family have encountered a massive roadblock regarding Andrew Nelson. He married Mary Elizabeth Thurston (daughter of Phineas Page Thurston, in Loudon County, Tennessee on 25 Jan 1872, and they had three sons, William Mack, Phineas Page and Oren. Supposedly, According to the 1900 US Federal Census, Andrew was born near Albany, NY in Jan 1829, his father was from Connecticut, and his mother was born in Maryland. Family legend is that Andrew wasn't his real name, as he supposedly changed it to avoid the law. Can anyone provide any help or pointers in how to find information about Andrew? Thank you very much.
