I know that children don't always carry the same last name as their father - the father, Harry Thomas Thomas Owen - and Hugh were born in Wales (1630 & 1662 - although another profile had Huge b 1668 in England). The grandfather is Thomas Owen. So... would the father's name have been Harry ap Thomas & then Hugh's Hugh ap Harry ? Is that how we got Hugh Harry as son of Harry Owen?
Also, any ideas on how Hugh Harry morphed to Hugh Harris? (just had a Harris profile merged into Hugh Harry)
