Am glad you are doing so well with this! I had meant to put in a piece about goiter-but forgot-not having your initial message directly in front of me before responding.

Other census sources to check. The best collection is Cyndi's list

http://www.cyndislist.com/

It has links to about everything you can imagine-Black history, military, state, cemetery, church records....

Check with state sources. Maryland has some very good ones online. Local libraries, city and townhalls, churches etc. The more you look, the more sources you will find. Best of luck!
