Thanks Glenda and Lorna for your help. Alexander is 71 years old in 1841 according to the census. His wife Catherine is 62 so that would have him born around 1770 and Catherine born around 1779. Their daughter Margaret is not on the census so I assume she has passed away. I also noticed that it asks if born in Scotland state whether in county or otherwise, so I assume if there is a n it means born some where else, right and it states whether foreigner or whether born in England or Ireland there is a slash so I would assume that it means Alexander and Catherine were born somewhere else. I have found their daughter Margaret born around 1813 in Old Kilpatrick. Once again thanks to Glenda and Lorna for your help. Margaret (Jean)
