I have indeed. The family is present in Randalstown in 1901 but not in 1911. One of the daughters married there in 1910, but I can't find any of them in 1911. I believe after the father died the family left Ireland, and I believe some went to Winnipeg Canada around 1918. Unfortunately there doesn't seem to be a will for the father Thomas Swan, although his siblings and father are all documented in wills.
