There were several Scott's on the Island turn of 19th C - the one you seek was probaby Thomas + Susannah ainsworth who had several children in Bride then 2 in maughold between 1806 + 1815 - they did not appear to marry on the Island - it is possible that the entries in the baptismal registers might help
There was a Scott family connected with the Quarry family at Ballavodan - see www.manxnotebook.com/famhist/v05n3.htm#45-48
