William and James Nelson in Saltfleet Twp, Wentworth Co, ON in 1826. William should be about 66, James should be about 29. William’s household has two males 16 or over (William and ?), two females 16 and over (Eunice and Sarah?), and two boys aged 0-15 (most likely Rueben Bloomer and William York). James’s household has one adult male (James), one adult female (presumably his wife), and four females aged 0-15. Four daughters!

No Nelsons in 1851 in Saltfleet. The Lamton 1851 census does not exist.
