I'm trying to get further info on my 4th gr grandfather John MacGregor (could be McGregor) born abt 1791 and married to Jane Cummins. They had a son (my 3rd gr grandfather) called Gregor who was born in 1818 in North Uist, Outer Hebrides,Scotland. Gregor was 21 when he immigrated to New Zealand on the ship 'Blenheim' in 1840. Gregor married 18yr old Catherine Fraser whose family travelled from Scotland on the same boat, same year.Apparently there was a MacGregor who sort refuge from persecution in the outer Hebrides and this may be Johns family but I cant find them. John was a farmer according to my family history.Can anyone help me?
