Many Irish people who settled in Glasgow claimed under the Poor Law. If so, they will have been interviewed about their circumstances and details of their home parish in Ireland will normally have been noted, as well some information on next of kin. The Poor Law records for the Glasgow area are in the Mitchell Library. They will normally do a look up, for a fee. Suggest you search for the family there. Otherwise it’s a needle in a haystack.
