I am also researching the McFeters / McFeeters / McPheters in New Brunswick. My ancestor is David (1822-1907) in Westmorland Co., and a James (1828-?) living nearby in the 1851 census. There is an Elisha (1827-1878) in Charlotte Co., and a William W. (bef. 1826-1995) in St. John. There is also a Ruth (abt 1831-?) in Albert Co. who married a MARSHALL. I honestly believe they are all related (siblings?), but have found no connection yet.
