Hi, My Maxwells came from Moneymore also. My grandfather Thomas Oliver Maxwell was born sept 28,1849 and came to USA around 1865. His parents were Oliver and Elizabeth Graham Maxwell. Tom had a brother John and he became an episcoplian priest in England. Oliver died young and once the mom died the boys were separated into different cousins. Tom was placed with Elizabeth sister, Margret Jane Shennan and later came to usa with her son John and an Ann but not sure if she was cuz or John wife. Hope we can connect here.
