Thank you so much for reaching out regarding your work so far!
It's so impressive to hear that you've managed to trace your ancestry back so far. It sounds like you've put a ton of heart and effort into learning more about your Irish roots and what these connections mean.
Unfortunately, discovering or verifying information from the 1700s can be quite difficult, as there may not be reliable documentation from this period anymore. At this point, what I would recommend is reaching out to the Co. Wexford Heritage
organization for more targeted information and advice. There's a contact us section at the bottom, where you can send your question, and they may have more insight into the historical truths behind this family story.
If you do learn more, and I truly hope that you do, please be sure to let us know!
