This came up on theDonald a week or so ago and I don’t believe anyone ever was able to show for sure they are related, other than the claim made in a tweet. If they were able to prove it, it would be huge.
I compared head shots and they aren’t in anyway close in appearance. I especially noted the front hairlines as men normally display their father’s traits. The name, is not all that common to my limited knowledge, so- discovering a family link may still be a possibility.
