Thank you very much for your reply. I had seen this census record on Ancestry but there is another record in 1861 for Thomas ?Harley living in Brussels St. with his wife Bridget and daughter Mary. I just don't know which, if either, is the correct record. On Ancestry I have indicated that the family living on Marsh Lane is more likely to be mine, especially as that Mary had a sister Bridget, but I can't be sure. Do you think I could do the same on Wikitree? I have plenty of records from the times of Mary's and Bridget's marriages but would ideally like to trace their family back to Ireland.
