I rechecked Arbory baptisms without any new find.
Searched Malew Baptisms 1770-1780 & years extra for
Henry. There were 3 illegit. births to mothers with no
father given Harry/ Henry/ John Henry [have details if
required. ]
N. B. Rushen film has a 27/03/12 statement " There
does not appear to be any entry of Baptism's in original
Register from 17 Aug.1777 to 27th September 1778 "
