From Dick Eastman’s OnLine Genealogy Newsletter comes this interesting press release about the Guild of One-Name Studies.
You may find a surname here of interest to you and your research. If not, you may want to start your own One-Name Study on their website.
I checked for “Pennington” and “Penington” and a couple of other variants but did not find a study. Perhaps this is an opportunity for the PRA to start our own One-Name Study.
