Chris Yes old Manx people would address Corletts
as Curletts even a few decades ago. The spelling is
now standardized as Corlett. There are a great number
of Corletts listed in the "phone book. I have two
lines in my tree. While doing my own searches today
I have looked out for you. Every page has several
Corletts BMD in Ballaugh & details are the bare
minimum making it extremely difficult to know you
are on the right track. LETITIA was not at all common &
sometimes spelt LATITIA. If your John & Jane were
twins that would help but maybe siblings or even just
cousins -children of Jno. 's brothers.
