Re: Ackerman sisters:NYC,Mary,Phebe,Jane,
I had a Richard or "Dirk" Ackerman and his wife Elizabeth Van Imburg (VanEmburgh, VanAmburgh)(married in Stillwater, Bergen, New Jersey abt 1766)left New Jersey as UEL (Dirk was next door neighbour and best friend to one of Elizabeth's brothers, James who was UEL)aboard the "Steady" along with Elizabeth's brother's James, Adoniah and John (Johann) from New York to Port Roseway, Nova Scotia, August 19, 1783. They all settled in the Tusket, Shelburne, area of Nova Scotia.They had Gysbert, Jacobus, Johannes, David, Grietje, Gideon and Abraham (Gysbert, Johannes, Gideon and Abraham all VanAmburgh family names).I have found Abraham, b. 1788 Nova Scotia, married to a Rachel Degarmo, Abt 1816 in Albany, New York.The Ackermans and the VanAmburgs were all Dutch Christian Reformed religion.
Hope that is helpful.Don't know much more the Ackermans
