Hi Annie
In the 1841 census I think 99% sure it's them living in 1 Abercrombie St Bridgeton[this is near the 1851 address of Kerr St Bridgeton] There is an AGNES 25 JAMES but I think it's wrong name I think it's meant to be JANE 9/THOMAS 7/ ISABELLA 5/MARY 3/ and also a PETER 1 all are said to be born in SCOTLAND not individual parishes perhaps she had another child between Mary and Agnes and Peter would tie in as it's Agnes's fathers name
in the 1851 Kerr St
AGNES 40/JAMES 18/THOMAS 17/ISABELLA 15/MARY 13/ and AGNES 9 this time Agnes pob Campbeltown/all the rest except Agnes Edinburgh and Agnes St John's dst GLASGOW
I think the Peter must have died will check on Scotlands people for him after
