How to record person known in youth by one name, assumed different name as adult?
With DNA test results (and help from a couple of DNA relatives, in both Ancestry & 23&Me), I recently discovered my GGF's actual birth name & family (from around 1880). He appears in several trees with this name, but no one has "public" records after the 1900 census. My family knew him by a different (but similar) first & last name all of his life, but no one has "public" records before a marriage certificate in 1907. (Note: He once gave apparently fictitious names for his parents.) So he is listed as two different people in the trees of the respective families. What is the proper way to record this? How do you handle a person later known only by an assumed name?
