You don't give a lot of information - names dates.
I have never come across a McGlynn coming from Bridgeton who appears on census but a Daniel McGlynn married a Mary Ann Leslie in St Mary's, Abercrombie St on 26 Nov 1874. She came from Barrowfield Toll, Orr St.
Born 1853 and died on 27 Nov 1916.
Perhaps your McGlynns came from Donegal after the turn of the century.
