The main source of information on Speake, Speak, Speaks, etc families in the USA is the Speak(e)(s) Family Association in the USA.:- Link to their website

Many of their members are descended from a single immigrant ancestor, Thomas Speake, wife Elizabeth Bowling, who died in 1681 in St. Mary's County, Maryland. However there was a possibility that a Thomas Speke son of Colonel Thomas Speke of Virginia was the same person as Thomas Speak in Maryland. It has now been established that they are not the same person, and that Thomas Speake of Maryland did not have any forebears in America. After much meticulous research, John S. Morris III wrote this article for the SFA Bulletin to set out the reasoning for this conclusion. His article is published here with his kind permission.

Due to the SFA's pioneering DNA project, it has been shown that there are many other as yet unconnected Speake etc. family groups in the USA. Please join this project and advance our knowledge of Speake research ! At present all fees are paid by the SFA for volunteers. Link to their DNA project

The exciting latest development in the SFA DNA project is that descendants of Thomas Speak of St. Mary's has been linked back to a Speak family who lived in Lancashire at the same time.
