Are there any sources for his parentage?
Asking because there are no notes in his About section and while the surname Rouillaut could have become Rowellett, Jean Pierre Rowlett Jr.'s father would normally be Sr. of the same name and not named Thomas. So wondering if he's connected to the wrong parents or if he just wasn't a Jr. They didn't use Jr. and Sr. back then, in any case, it would have been Jean Pierre Rowlett I and Jean Pierre Rowlett II, most likely.
Thanks for any clarification / corrections.
