Hello and welcome to RootsChat
If I have the correct John Boyde in the census -then it looks unlikely that his father was James - possibly his grandfather was James???
1851
Michael Isle of Man
William Boyde head married 35 ag lab Lezayne? I.O.M.
Mary wife Married 31 Andreas I.O.M.
James brother unmarried 37 ag lab Michael I.O.M.
Mary sister unmarried 41 House servant Michael I.O.M.
JOHN nephew 13 tailor's app Michael I.o.M.
HO107 2523 294B 3
so John was living with his Uncle - James would be his uncle too -as he was unmarried. Mary was unmarried - and so would be John's aunt -or maybe his mother if he was illigit???
Do you have marriage cert for John ??
1841 - only gives county where born -and no relationships
