Among my great Aunt Bertha’s things was a handwritten note with various birth and death dates. One portion says:

Isaac Lenox from near New Amsterdam Holland. May 18, 1838, came to America when a very small child. His family all died soon after they arrived and the family by the name of Brown raised him. He enlisted in the army, 13 Regiment Michigan Volunteer Infantry, ‘Civil War’.

Another family document tell us that that Isaac “was the father of at least one son, Bishop Lenox of the Catholic Church in Michigan before being married to Mary Defries. He worked as a railroader in Council Bluffs, Iowa and later had the first blacksmith shop in Hennessey, Oklahoma in 1893.”

I have been able to verify that Isaac used both surnames and many details of his life after the Civil War; however, his life as Isaac Lenox (Lennox) is still a mystery.

Isaac Brown was my paternal great, great, grandfather.

No Story Too Small offered a challenge: have one blog post each week devoted to a specific ancestor. It could be a story, a biography, a photograph, an outline of a research problem — anything that focuses on one ancestor. 
Each of my posts for this challenge will include in the title “52 Ancestors Challenge” and will have the tag of 52Ancestors.
