Thank you Andy and manukarik. I will consider looking into those records.
Just trying to help
you say...........
Given his new last name is a common name (changed from Vogelfanger to Lewis) I know it will be more difficult to find him.
There are two records for Lewis. What was his Christian name?
If you have his actual Date of Birth that would help.
Did he marry?
What year did he enter the USA?
Maggsie
Maggsie, yes, his name was Samuel/Sam Vogelfanger. I have some good information on him from Ancestry and FamilySearch, as well as primary documents (postcards to family members etc before he entered the army). He was originally from the Austro-Hungarian Empire, born 1886. He entered the USA in 1905 (records of which are on Ancestry), he married and had two children by 1916, but "disappeared" in 1917. On my great-grandmother's Naturalization application in 1925 it states: "Have not seen husband in 8 years", which mathematically dates back to 1917, when it would appear he joined the Army (as I found his enlistment card from May 1917). I have a couple other family stories that give a perspective on why this may have happened, but honestly I will never know the true reason. When I found his Naturalization record (dating to 1919) he lists that he does not have a wife or children. Soon after that he attempted to change his name for the first time. Now in 1921, the latest record I have, it shows he still lists no immediate family, and trying to change his name for a second time. He still lists his profession, an essential piece of information, as that ties in to what is known by the family and from previous records on Ancestry.
So I have confidence I have "found him", but am looking for tips on how to continue the research, post-1921, now that he is going by a more common name. He does not appear as a Vogelfanger in the 1930 census, which would be the next available Census, if he was still alive then, so either he is going by Lewis or Vogel (both of which are far more common).
