I'm trying to trace my birth mother Agnes Teresa McIntyre (nee) McDonagh. She married my father Alexander McIntyre in Glasgow in 1965 and had two children, Mary Alexandrina born 3/1966 and me, Robert Alexander 5/1967. We were left as children at Deepdale Hospital, Preston Lancashire in 1967 and eventually adopted into different families. I believe my parents were divorced in 1980. I can find no trace of her before she married my father (now deceased (1991)) and would like to know more of where she was born and where my grandparents on my mother's side were born. I can only find their marriage certificate, but there is no clue as to where she was born and I'm now working on the assumption she was born in Ireland to an Irish traveling family.
If anyone can help me trace my mother's lineage back or can guide me to information where I can find this information, then that would be very much appreciated.
