Hello Barbara, This is not going to help your quest but all I could find was in"Some Descendants of Nicholas & Sarah (Oliver) Rideout of Maugerville, NB" , compiled by Stanley Corey. This booklet was at the public library in Woodstock, NB.From page 12, listing the children of Nicholas Rideout and Rebecca Treadwell (his first wife) and Jane Munro (his second wife) 7. Mary Ann. She married James Swim 25 Dec. 1829 (York County rec.), but had died by the time of the 1851 census.The James Swim of Brighton, age 48 in 1851, was presumably her husband, but in 1851 his wife's given name was Ruth, age 27.The four children with James and Ruth in 1851 were Mary, age 8; Olive, age 6; Joseph, age 3; and William, age 1.But there is nothing to indicate that Mary Ann was the mother of any of them.
