I have also seen the baptism of a Mary Ann Lynch and siblings with mother Mary McKenna and she is in censuses.
One thing that is a bit of a puzzle, is that with a marriage in 1912, you would expect a child before young George.
I have seen a George Earle born 1890, who is a waiter on ships 1910-1912. Those are the only records but if he was at sea after marriage, that might be a reason.

By various searches, I think I can connect him with a family and he would be born Liverpool.
However, that would be contradictory to the first post re Ulster!
Additionally we are unable to post 1911 information - other than the indexes.
Just reread your post rosie17 and the above info re the waiter, doesn't fit with a father William
