Have you ever contacted any Granthams in the Red Level area today? There are several listed in the Andalusia area phone book (I do not live there-just have a book). You can get the same info from Yahoo's People Search site:http://people.yahoo.comhttp://people.yahoo.com
Perhaps someone there has worked on the family tree.
Just open the Covington People link. You wiil see current articles on families as well as the archives for 1999-2002. When you open the 2002 link, scroll down to the bottom to get the new families that are added each week. You may want to also contact Curtis Tomasson who writes the article by his email address or phone listed there to see if he has and info on the Grantham family. He can also give you information on how to order the Covington Co AlL Heritage book series which has just gone to print which may prove helpful not only on your family but also in helping you to understand the life and times of your people.
Also if you think you family may be related to neighboring Pike Co AL Granthams, I can put you in touch with someone who is familiar with that branch. I believe some of them did go to Covington Co.
