I thought you might have found the info, your post was so long ago, but I had just received parish records the day I saw your post that listed Shadrach, so I replied.
My connection is through Margaret Dorrel, who married Robert Money in St. Stephens Parish in 1706. Margaret was the daughter of Nicholas and Christian, and sister to another Nicholas Dorrell. I have a few bits and pieces of the Dorrell line, and not much substance.
One of the most interesting "tidbits" is that Christian may have been the daughter of Mans Anderson who came over on the Kalmar Nyckel.I haven't followed up on this yet.
The records I received listed Nicholas Dorrell, born 1727 as the son of Nicholas and Elizabeth.I am guessing that this Nicholas is my Margaret's brother, but I have no information on him other than the few parish records listing his children.
