Samantha Clark of Charlotteville Township, "mantuamaker," purchased land at Charlotteville Township from her father on 3 Jun 1823. On 14 Jul 1830, James B. Clark of Ancaster purchased land at Beverly Township, Wentworth County from David W. Barnum and then sold it on 25 Apr 1832 to David Rymal. The family moved to Newark, New Jersey where her son John N. Clark, heir-at-law, lived when he sold the land of Samantha Moore Clark, deceased, to Charles Francis Beaupre on 15 Feb 1848. At that time, his father James B. Clark was "late of Newark, New Jersey."
From 'The Loyalists in Ontario' comes the note:
"Barnum.. Nathaniel Bunnell, settled Charlotteville, his children
1. David Wheeler Barnum, got his O.C.4 Dec 1834
2. Charles D. Barnum O.C. 17 Oct 1839

O.C. stands for "Order in Council", which means that they were now either married (if female) or over age 21, and could then claim their free land grant as a child of a Loyalist. In the case of males, it gives you a good idea of when they were born. All those with no location given were in Charlotteville, near their father.
