Hello Michael
I am a descendant of the Callins from Patrick.
Are you studying the Callin name? If so I may have some useful information for you.
The Callins were centred in and around Foxdale, upper and lower, Doarlish Ard - they also spread to German (Peel). There are a few visible/readable gravestones at Patrick, one at Foxdale but many at Peel cemetery, old and new. Also Braddan and Douglas Borough.
I have an Elinor Callin marrying a Charles Radcliffe in my tree and few resultant Radcliffe descendants - but Callin has been my focus.
I am in touch with several living Callins and other relations in England, Wales, Dubai, Australia and Canada, as well as the Island.
If you want to discuss this further, please let me know.
Paul
