Hi Dave,
On the SouthWest Ohio group I only have a few links for Brown County I have to do some more hunting around for some more. If you can give me some names and dates I can do some hunting for you. You can go to the SouthWest Ohio group and look at all the Discussions and there is one in there for Borwn Co. and check out what is there for now and I will let you know when I add more.
When you did it before did you check out the rootsweb.com site or the LDS familysearch.org site? They are good free sites so are the GenWeb sites.
You can send any info to my home e-mail if you don't want to post that info here, do you have my e-mail address? If not let me know I do have yours and will send you a message.
I just got done doing some research for EZ's dad;~)

Dave, I just did a quick search of the 1880 census in Brown Co. and there are about 60 some Baird's there, that includes all family members. Do you have any names that far back?

Dave do you have a library card? I used mine to look at the 1880 census and found 2 franks this morning. Both children one in the home of George and Mary Frank O. is 4 years old. And one in the home of John Jr. and Elizabeth this frank is 2 months old. I am off to work now but will look more when I get home.
