I think your Robert Howieson and his wife, Nancy Wadleigh is also known as Nancy Woodby, are parents of James B. Howieson, born 10/30/1820 in Shipton, Quebec, Canada - this is near Kingsey. James B. moved to Elmore, Vermont and died there in July 1901. His Death Certificate showing Robert and Nancy "Woodby" is on file with the Elmore Town clerk. James B. Howieson is the father of my Great Grandfather, Elgin E. Howieson. I found no information in Elmore about John Wadleigh (Woodby??) Howieson.
