Hi,
I don't have a direct link for you, but did notice some things in your post that may be clues that both can use. I see that you posted that, "(R.B. Garrett may actually have been R.R. (Richard Roper) Garrett." I have a Rachel Roper that married into the Winder family in my line. She married George. W. Winder. Rachel was born Abt. 1838. She married George W.Winder on May 11, 1872, in Hamilton Co., Illinois. I do not yet have information on Rachel Roper's family line, but she may be from your line. I found it interesting that you have both the Roper and Winder names. I beleive that there is a connection somehow here. My Winder line is from all over the country, with many Winder branches, seems to be everywhere. There were Winder family from Virginia.
Please contact me at
snickeroomom@worldnet.att.netI might be able to help you find more on this part of the family.
