Valerie, you may be one of the lucky Lounsburys, meaning no dead end back to R & E Lounsbury. The Lounsbury "family" has a very well organized network and an active "Lounsbury Tree" publication. Your family history back to Richard and Elizabeth can be found in John M. Freund's wonderful compelation titled "Some Descendants of Richard Lounsbury of Rye New York". I suspect that You will receive many replies to your Query so I offer my help only because I am the first to reply. Be reminded that Mr.Freund's work is a compilation, the verification of each family must be left to the researcher. To start you off I have a copy of Robert Lounsbury's Will in which he mentions his son Townsend. Send me a E with your address and I will get you started.
