The Buercklin/Berkley/Barclay family of Berne, Albany, New York, USA

While I am waiting for the 1812 Military Records for Martin Ebert to arrive from Washington, D.C., I decided to look at the 1790 US census for Rensselaerville Town, Albany County, New York again.
I found the entry for John Ebert, and decided to look at the families next to him in the census.
The 1790 census record has:
Berckley, Peter
Berckley, Henry
Berckley, Christian
Ebert, John
Berkeley, Eberhart

John Ebert and his family were surrounded by Berckley's.  I did some research on this Berckley family and discovered they were all brothers!  It made me think, could John Ebert's wife be a Berckley?  I have not found any record for her christening, however, I have found 12 children of Eberhardt Buercklin and Margaret Hoss/Hoff (the parents).  There is a gap between their son Johannes Buercklin, born 11 March 1752 at Wiel Im Schonbach, Wurttemberg, Germany and their son Andreas (Andrew) Buercklin/Berkley/Barclay born 30 November 1756 at Albany, New York.  I had determined that Mrs. John Ebert was born about 1755.   The family had emigrated from Germany between 1752 and  1756.  Could Mrs. John Ebert have been born at sea? Probably not, as she is not listed in the immigration list.   Ancestry.com has an index with this family on it, but it only gives the spread of years the index covers, not the year of emmigration:

If anyone has access to the above book/record, Emigrants from Wuerttemberg... it would be interesting to find out when, on what ship they came over, and who else came with them.  I will continue to look for this info, but if anyone else can find it, I can publish the info on the blog.

By the 1800 US Albany census most of the Berckley/Barclay families had moved away, most went to Dundas County, Ontario, Canada.  Some stories I have found on the internet claim these Barclay families were Loyalists.  I did find one of the brothers, Joachim Berkley, still in Albany County, New York, in the 1800 census.  There may have been others.  The name is spelled many different ways, and even soundex searches don't catch all of the spellings!
