Leonard was a capt. of a ship, or that's what we know. (Leonard Paddock) It was not uncommon that these sea faring men traveled a lot. If you don't have a name (or marquee) of ship, it's even harder. But I would look at any mention of him in Ireland, or british ports most commonly known back then. Also, look for any association he may have with "dutch" as well. I only say that because it was brought up somewhere (trying to bring that info up) that huegnots had some good relations with the dutch, and the dutch came to American (before it was America). Robert may have known Thomas Willett because of that, and there may some relationship to Leonard Paddock and Thomas Willett. (John Paddock was given to Thomas after Robert died). Thomas Willett acted as an arbitrator for the english with the dutch. (also note: New Amsterdam, New Netherlands were claimed at first, but now New york, etc). It was known Dutch ships were popular with traders. It looks like he actually grew up for part of his time in Holland. He did get involved here, in ship building. I find this to be important b/c it may lead you to more info on Leonard Paddock (Peddock)on who he was, or where to find him. If I find something, I will let you know.
