An address given by Alexander Jones in 1855 is recorded in a book about the Welsh descendents who were involved in the American Revolution. The address was delivered in the Welsh Congregational Church which stood on Eleventh Street, New York. At the request of the St. David's Benevolent Society it was given on the eve of St. David's day, February 28, 1855. The following is a copy of the title page:
The material was reprinted by the Genealogical Publishing Co., Baltimore, MD in 1968. It was then reprinted in 1989 by the Clearfield Co., Baltimore, MD.
The book contains a large number of "Appendix" discussing the Welsh language, history, and chronology. It also contains the address of the Rev. David Jones at the Fort of Ticonderoga when the enemy were hourly expected in 1776.
I suspect the book is not widely known, so I put the reference for those who might be interested. It is a fun reference to peruse.
