Richard,
I am assuming you are following up on your previous post (10/10/99.) My interest in Berlin is strictly from a slavery perspective. Should you need family information on the COHEN's, I would suggest you check the UK government BRITISH NATIONAL ARCHIVES. Slave owners in the colonies were required to document certain information with the UK government; hence, this maybe a source of information for you. In addition, you could also use FAMILYSEARCH.ORG - do not limit your search to Saint Elizabeth; you should also include WESTMORELAND and MANCHESTER (possibly all the parishes,) I believe these parishes were once a part of Saint Elizabeth. Also, remember variation(s) in spelling. There are a lot of COHEN'S (with variation in spelling) on FamilySearch.
Good luck in your quest.
