GenForum

The last free genealogy site that I mentioned in today's initial post was GenForum.
http://genforum.genealogy.com
When you get to the home page you will see that there are forums for many many surnames and also forums for states and counties!
These are forums where other genealogy researchers are posting queries and/or information related to that surname or counties and states where those family members lived.

I can spend hours looking through the sites related to my ancestors.
For Fred and Susan T Knowles Brown there are many places to search in GenForum.
Under Surnames
Brown
Knowles
Under States
Ohio
Iowa
Under Counties
Ringgold
or Trumbull
or Ashtabula
(the last two being the counties in Ohio that Fred and Susan lived in prior to moving to Iowa)

This is also a great way to find out about female family members. Women often lost their last name and legal rights under English law.
Write the woman's married surname to bring up that forum, then write her maiden name in the search box related to that particular forum. Often information about their parents or siblings can be found. Then search the surname forum related to her maiden name and use her married surname to find out if others have information about her.

Fun eh?
