Got that information from another cousin who has done extensive research into the Cummings's of Tircrevan & Ballycarton. George Cumming was born in Paisley, Renfrewshire, Scotland in 1778 his parents were David Cumming & Elizabeth Lang. George came over to Limavady about late 1790's- early 1800's. Married Elizabeth Taylor and died at Ballycarton in 1854. (They had 3 children David , James & Mary.) I am descended from James.
David Cumming & Elizabeth Lang had about 12 children spanning 20 years. George was their 4th child. If you do a search on Scotlands People you will find all the children of David & Elizabeth Cumming. They were Presbyterian and married at Paisley Kirk Low Parish about 1776.
I have also sent you a personal message.
