hi marie ,
as I am a new member i cant email you, but it does seem to be very confusing I have 3 birth certs for patrick Dougan 1841.in the1891 census this is true and corect by my mothers info, I also have a patrick Dougan birth 1873 maried to a margaret Mcdonald . I think this is the son of my gr Gr grandfather and one birth for 1876 father edward mother Sarah Kelly Married in ireland .i Know that the dougans from Bridgton in Glasgow were a big family as my uncle john told me that when Patrick was 90 he was in a paper and my uncle was one of 130 grand kids his son john my gr grand father had a glass eye and worked in the Gas Works in Glasgow were he lost his eye.hope this helps maybe you can email me and we can get it right as it sounds like you may be from patrick born 1873 who is the son of my Patrick born 1841
Thanks again jeanette
