Thank you so much for your help here & on Ancestry, I greatly appreciate it!
To update you, I found a tree on Roots Web which gets this Shreve family back to a Benjamin Shreve of Loudon County, Virginia. The man who has done it, Mr. Maloney (if memory serves correctly - have it bookmarked), has listed sources so I do trust it & will double-check it since that is always the best thing to do no matter how many sources are cited. I believe I may be closer now in finding a link between my friends Shreve family & my own.
It never ceases to amaze me what a small world this can be sometimes, just this summer I found that one of my Dad's best-friends since high school who's also one of my Godfathers & my Mom who has been one his wifes best friends since elementary school have family in common. There are many other examples in my research & I am sure everyone has some type of small world example.
