I'm "brick-walled" on my Johnson line. My grandfather, Roscoe Conklin Johnson changed his surname from Johnson to Johnston in abt 1900 after he had moved to Montana from Michigan.
The father of Roscoe Conklin Johnson was William A. Johnson, born abt 21 Apr 1833 in New Brunswick [now part of Canada, died 16 Sep 1894 in Tawas City, Iosco, MI.
The names of William A. Johnson's parents are unknown to me. Several censuses showed that his mother was born in New Brunswick and his father in Maine. This is my brick wall.
My second surname of interest is Hackett. I'm not so much looking for info on this line as sharing what I already have. My earliest known Hackett ancestor is Capt. William Hackett, born abt 1635 [place unknown], and his first wife was Sarah Barnard, born 29 sep 1647, Salisbury, Essex, MA.
