Hello Charles,

You wrote that Margaret Cregeen married Alfred Scott in Kirk Rushen on 2nd August 1868.

If you haven't already checked this marriage record it should be the first thing to do, because it should have their fathers' names and occupations, as well as addresses, and sometimes the ages of the couple, and can save going down numerous dead-ends.
Even though you have listed several fathers with the same name, their occupations given there should help sort them out if her father turns out to have the same forename as others.

See the parish register copy at the Manx Museum Library or on LDS film no.0106194 available worldwide at their Family History Centres (see local phone book under 'Church of Jesus Christ of Latter-Day Saints' - FHCs are open to all).
