General Links

First, Mailing lists:
Send an email with just the word SUBSCRIBE as a subject and in the message to SURNAME-L- request@rootsweb.com. Replace SURNAME with the surname you are researching, type it in all CAPS. These lists are made up of people who are researching a specific name. Don't be surprised to find distant cousins on them. Don't be disappointed if you don't make an immediate connection. It would also be a good idea to join county mailing lists (NYERIE-L or TXRUSK-L). They are mailing lists for people researching in those counties. Just add the -request@rootsweb.com to the end of whatever list you want to join. The address for posting to these boards is the same, but leave out the "-request" (WOODLAND-L@rootsweb.com).

GenForum:
http://genforum.genealogy.com/
Type up a nice query to post on these sites. Try to be as specific as you can. Something like: "I am looking for information on Mary Jones, born (birthdate) (place); died (date) in (place); married John Smith (date) (place).
