There is definitely a link between our families. The fact that Richard was a "shoe cutter" and Wellington's middle name was Highfield make it a cinch. My Michael Faught was a shoemaker in Dublin as were many other Faughts. Where and how we link up is the puzzle. I saw that one of Wellington's brothers was named Francis. There was a Francis Faught whose family emigrated to Ontario about the same time your family came over. Is it possible that your Richard, my Michael, and Francis were brothers? That could explain the "Highfield" middle name (my Michael married Mary Highfield).
When I received your note I started looking into the LDS records and found the marriage date for Richard and Mary Ann, but the location shown was St. Michael's Parish, Limerick. That would have made sense since the Faughts didn't seem to go to Dublin until a bit later. Is your family Methodist? Many of the Palatines became Methodist after hearing John Wesley speak. They had lost their German roots and church and found Methodism a good substitute. My ggggrandfather was married in a Methodist Church in New York City and had worked as a sexton in a Methodist Church in Dublin.
Also interesting that Richard and family lived in Boston in 1855. Did they move to Maine? In researching the family I found Faughts who lived in Maine and wondered if any were related.
Am looking forward to hearing from you...this is really exciting as I had never found any other Faughts who seemed to be related.
