Walter,
Working backwards. Alexander
Ramsay died in Bartonholm,
Parish of
Irvine on 10/4/1900 - he is the widow of Ann
McGregor and the son of Alexander. He died, aged 77, of cancer of the lip. Bartonholm was a paupers residential home and hence the fact that Alexander died there isn't a good representation of where he lived his life - old people were sent there from locations further afield.
If the 77 year old is fairly accurate, this makes Alexander born in late 1822 or early 1823. There is no early 1823 but there is an Alexander born on 24/3/1822 to Alexander
Ramsay and Marjory
Anderson. This birth was registered in
Crail.
The only marriage I can then find is Alexander marrying Anne
McGregor on 30/10/1837 in Clackmannanshire. Alexander was a brickwork labourer and probably worked on various construction gangs all over the country - so these movements are not impossible.
I hope this helps - it isn't really an Ayrshire lead at all - but perhaps that is what has been frustrating your efforts to track this one down - best wishes,
Robert
