Back to the La Mothes, you can see their burials in Lezayre on Brian Lawson's index: http://www.lawsons.ca/burials/l_01.html (Dominique Lamothe recorded as Doctor Lamothe), but Ramsey ones are not there.

Dominic LAMOTHE bapt 9 April 1775 Malew, son of Dominic LAMOTHE & Susanna CORRIN [IGI]

These extremely detailed accounts of the family come from Frances Coakley's website Manx Notebook:
