I believe my great grandmother Charlotte Louise "Lottie" Vradenburg Winslow (8/18/1861-5/28/1941)is your Lillie Mae's sister.I do not know very much at this time about Chester Vradenburg (c. 1835-?) and Mary Brooks Vradenburg (c. 1839-?), but I have lots of family info. that I am currently going through.If you would like info. on "Lottie" and her descendants, I will be glad to forward.
