Do you just need information on the Lee family, or are you looking for information on the Linthicum/Williams, etc. lines?
I am descended from Frances Linthicum, sister of your Mary, another daughter of Francis and Eleanor (Williams) Linthicum, and can trace their parents lines back several generations. I am afraid I do not know anything on the Lee family, but I know a mutual cousin of ours, William Winter, who is descended from that line, too.
If you don't already know him, write to me directly and I will give you his address. He is supposed to be sending me a packet of information through the "snail mail" but I haven't gotten it yet, and I don't know if he would have included any Lee information.
