I'm currently working on Peel families - the progenitor of this family is John Gregor 'now of this parish but late of stetin in prussian pomerania', who married dorothy crossendale als colvin on 13 Nov 1763 (Peel) (probably buried Ger 5 Feb 1801)- I can only find 1 child - John Gregor (Ger 1764-09-30) - who married Judith Bart (can't find this marriage in German PR - the name Bart I hadn't seen before) and had John (Ger 17921018) George (Ger 17940309) Ann (Ger 17951206) Benjamin (Ger 17970820) Dorothy [Grygar](Ger 18000321 prob bur Ger 29 Oct 1818) - Judith buried Ger 24 Apr 1829
(the name is spelled in numerous different ways (Gregor grigger grygar ...)some of which do not produce the sound soundex value thus IGI searches are frustrating)
