I've just discovered that I may be related to John O'Connor Smith through his daughter Sarah Smith. I am pursuing this lineage as a supplemental to my DAR membership and will have to prove that Sarah was indeed a daughter of John's. The DAR has proven John's daughter Mercy and son Zedock (Zadock). This thread has such wonderful information that I will read thoroughly. But if anyone has information (proof) of Sarah being John O'Connor Smith's daughter, I'd appreciate hearing about it.
