As is the ancestry of all but one President of the USA, Biden’s family is mostly descended of the British Isles, with most of their ancestors coming from Ireland and England, whilst also claiming descent from the French.
While I have little interest in him and his family, I find it surprising that while Obama’s and Trump’s blood types came my way fairly quickly, I have yet to receive word on what Joe Biden’s blood type is.
Is he Rh- like most (not all) U.S. Presidents?
