No, the man I'm matching to is my maternal Aunt's husband... Surprise!
If it was a paternal uncle I probably wouldn't have pinged that there was an issue.
In that case you are back to square one. You already have matches on your maternal side.
My advice, for what it's worth, is to stop fiddling about with your tree!
Either matches will start trickling in or they won't. If you follow the advice already given, and nothing at all turns up, you may have to consider that the man who brought you up was not your biological father. But to me, that seems a long way into the future. Have you any closish paternal relatives who would consider testing?
Neither of my brothers or cousins wish to be tested, none of my uncles or aunts still living, unlikely to have wanted to be tested. Similar things happen in other families. So that rules out me finding any close matches. If nobody in your paternal side has been tested, no matches will appear.
The more people who get tested, the more matches for all of us, even if, as is often the case, they have no interest in genealogy.
Wait and see what happens in the next few weeks, carry on building your real tree, follow the girls as well as the boys, go sideways as well as backwards. You may come across a name you recognise.
