Hey Lynn. My great-great-great grandfather's sister, Nancy Hariel, married Elijah Lee who was the son of John Riley, son of Samuel. In my notes, I do not have a William J. Lee but a William S. Lee who is another son of Samuel and brother of John Riley and Reuben. According to my notes, he was born around 1797 and married Margaret Collins. The William J. Lee I have in my notes was the son of Reuben, son of Samuel, and born in 1824....not a brother of Reuben. So William J. and Elijah were first cousins.

As for ties to General Robert E. Lee....

Henry Lee's son Henry b1730 and Arthur Jr are 1st cousins
Henry Light Horse Harry and Sherwood would be 2nd cousins
Robert E and Samuel 3rd cousins and each step below that is removed
John Riley/Reuben/William S. once
Elijah/William J. twice, etc.
