There is a reason Bolyard can't be found any where this is because it was Not originally Bolyard it was either Baliote, Baliotte, Balyeat there were several spellings but somehow it has changed. Whether this was because of Illiteracy because most were poor farmers or just a fluke who knows. I only know because my great Aunt Lora Anne Has a family tree and when I started my search my mom told me to talk to her. If you find anything let me know I'm still trying to find information. Hope this helps you in your search. At one time I found a site I track them back to the 1300's. I did not book mark it though and now I trying to find it again.
