Has anyone done research into the Hartt families of New Brunswick or Ontario? My great grandfather , James Hartt, entered Michigan about 1850 from one of these provinces. The earliest census records, 1850, has him born in Canada. It appears most Of Isaac Hartt's children immigrated from New England into New Brunswick in the 1700's and this is probably the family I'm looking for. Any information on these Hartt's (2 t's) would be appreciated. Geoff Hartt
