Hello, Shane.I found this information on Temperance in the Gilbert Family Forum.I does not address the Clere-Gilbert connection.I'll look through my files again to see if I have anything further on Clere & Gilbert.

"According to a published genealogy called "Alsop's Tables" by Jerry Alsup, the Temperance Gilbert who married John Alsopp on May 1, 1617, was the daughter of "William Gilbert of Mickleover." Since the Alsopps were from Derbyshire, I suspect that Mickleover is or was in that shire, although I have not verified that. I found the book at the DAR library in Washington, DC.
"Probably the most famous descendants of Temperance were the political columnist brothers Joseph and Stewart Alsop, who were at their peak probably in the Kennedy years."
