Would appreciate advice anyone can offer on this one please.
My ggg grandfather was born Angus MacMath in Campbeltown in 1774. He married in Campbeltown as Angus MacMath in 1806. His children born between 1807 and 1828 in Campbeltown, including my gg grandfather Hugh, were baptised as MacMath or McMath. His last three children born between 1830 and 1837 in both Campbeltown and Old Monkland, Lanarkshire were then all baptised as Mathieson. In all censuses up to his death, Angus and his wife and children were recorded as Mathieson.
I understand that Mathieson and MacMath basically mean the same in Scotland, but I am at a loss to explain why the family's name changed from MacMath to Mathieson around 1829-1830.
Can anyone please shed any light on this?
Thank you, Paul (in mostly sunny North Queensland, Australia)
