Hi, I've tracked my wifes branch of Moughtins from James Arthur b 1818 Jurby, to James b 1794 Ballaugh, to Arthur b 1750 Jurby, John b 1717 Jurby, Patrick b 1684 Jurby and Arthur b ~ 1650 Jurby. I'm not sure which branch of Moughtins you want to know about. I have quite a lot of info and many Moughtin Wills from the 17th & 18th century. There were quite a few Moughtins, mainly in Jurby.
Regards,
Don Lawson
