Do you know if your McAllisters were from Moneymore in Northern Ireland. I have John McAllister and his wife Margaret Jane McGill. There known children were Bridget Annie Catherine John Susan. I think that they might have had a Patrick as well as Margaret Jane McGill's father is recorded as Patrick a Land Surveyor. My John McAllister and Margaret McGill married in Moneymore 1857
