Thomas bp 29 June 1815
Joseph bp 2 July 1817
Anne Blamey bp 4 Apr 1819
Charles bp 1 June 1828, born 2 Sep 1826
Anne's middle name would seem to confirm this marriage 6 June 1814 for Christopher Harris & Catherine Blamey, witnesses don't appear to be relatives as they witness other marriages on the same page

Christopher Harris head mar 59 mine blacksmith b. St Agnes
