I've just found this thread, I have the Frights in my tree.
I have got back to John Fright b. about 1685 who married Pleasant Johncock in 1707 in Elmstone, Kent. He has a son called Abraham b. 1710 so I would imagine that your Abraham is John's brother (I don't have any siblings or parents for him yet).
None of my Frights are in Faversham, they seem mainly to be in Elmstone, Birchington, Monkton.
Pleasant seems to have been a recurrent girl's name in the family, apart from Pleasant Johncock I have found a Pleasant Fright b. 1719 and another one b. 1752, niece of the earlier Pleasant who was christened at St. Nicholas-at-Wade in 1720.
Hope this is of interest.
