"File contains a document executed on 1 February 1844 by Daniel BROWN of Truro, Colchester County, Nova Scotia, stating that Titus KNAPP died on 13 June 1828 and his widow Catharine died testate on 11 March 1841 and that Catharine Isabella KNAPP, grand-daughter of Titus KNAPP, married Daniel BROWN on 4 July 1839 and on 11 August 1842 was of the full age of Twenty one years."
[1842-21=1821 for approx year of birth for Catharine Isabella (Knapp) Brown] https://www.wikitree.com/wiki/Knapp-3491 is likely to be the same person.
[I don't have information on the birth of David Brown, other than to say that most people don't get married before the age of 15. 1839-15=1824. both the bride and groom would have to have been born before 1824.]
