John,
My name is Wallace Olney. Your grandfather Thomas Moore and my grandfather William Robert Moore were brothers, sons of William and Catherine Ann Quayle Moore. Grandfather Moore (William Robert) was kind of an out-cast from the family because he and my grandmother, Ellen Ann Greaves Moore joined those "Wicked and abominable" His father told him that NO MORMON WILL EVER DARKED My DOOR.. My grandparents emigrated to America moving to Preston, Idaho. Grandfather never saw his parents again and they would not give him any information on the family. So it has been difficult piecing things together. Through research I have a great deal of information on the Moore and allied families on the Isle of Man.. Nathaniel's father was indeed JOHN MOORE. this is verified on the marriage certificates of Arthur and Robert Moore where he is listed as FATHER. I would love to hear from you and exchange whatever information I have that you are unsure of.
