Using Ancestry to find my great-grandfather I also received a bonus, matching with a woman who is my half-niece and two of her three children who had also tested their DNA. I will add my previously unknown half-brother (now deceased for over 50 years) to Wikitree only with the assent of his two daughters. But I have a question about how to enter his name. I would think not Hayes, but probably the name he was given at birth (his mother was married when he was conceived and born). Her husband abused her, probably suspecting that the baby was not his. She remarried and her second husband adopted my half-brother, changing his last name and adding a middle name.
Assuming the first husband was named Baxter and the second husband was named Johnson, should the entry for the birth name be Ronald Baxter or Ronald Taylor Baxter? All of his life after age 3 0r 4 he went by Ronald Taylor Johnson.
After reading the help pages, my inclination, if we add him to Wikitree, is to give his birth name as Ronald Taylor Baxter, then add Johnson as his later last name. There will be some explaining to do in the biography, all of which will be with the approval of his daughters. His mother left written documentation of the abuse she suffered from her first husband. Of course he will be merely mentioned in Ronald's biography and in his mother's. Wikitree will show my father as his biological father. There can be no other biological father as my father was an only son and my half-niece's DNA matches with people who descend from the same people as both of my paternal grandparents.
