Hi Elaine, Do you have a John Halliday who married Margaret McQuaker in your tree? I have no birthdate for John, but Margaret was born circa 1796. She appears in the 1841 census in Creetown (Kirkmabreck), with presumed daughters, Jane and Margaret, both born circa 1821 and a 3 year old John McKeand which I believe is her grandson and my husband's gr.grandfather. I believe McKeand is a misspelling on the census enumerator's part as John eventually spells his name Kain. John and Margaret (McQuaker) Halliday were the parents (according to the IGI) of Elizabeth Halliday (b. 1815) who married John Cain (Kain) in 1838 in Whitehaven, England. Thanks, Conni
