Ian, I am sure you are correct, the descendents of the family were all Free Church.
John Gunn b. Lanark never been able to find his birth his age changed constantly in the records, died 1894 age 87 approx
Married Isabella Ross 1835
Children\Mary, Peter, Thomas, Margaret, Dolina, John
Isabella died and he remarried
Betsy Gunn 1851
Children
Isabella, Catherine, Helen or Ellen, Euphemia, William my Great Grandfather.
Poor Isabella is described as Imbecile, or lunatic although her family looked after her until she died
in1908 age 56
will be interesting to see if you find their names among the free church records
Thanks
