I am the Rootsweb Administrator for the PIGGOTT (all spelling varianta) surname list. We have an active list, and your chances of finding information on your line are reasonably good if you post as much detail as you know to that list. Give us names, dates and locations, and our list members will at least try to find additional information.
If you would prefer to send your information to me, I will post it for you.
My e-mail is: firstname.lastname@example.org
