Thanks. I had looked at that site, but looked again and found no new ones. The ones on that site boil down to the ones I already had. Use of names as well as initials makes it look like there were more than ones who served. Thanks for getting me to think more. I just noticed a note about one who was not on that site, Albert Amacker who was one of 4 brothers from Louisiana ( one actually served in a TX unit). I can't remember where I got the info that Albert died of camp fever at Belmont , KY on Dec. 21, 1861. Another brother died as well as 2 of their 1st cousins.
Will have to search more to solve identity of the mysterious "Doctor Amacker."
