Thanks for the permission to view your family tree on Genes Reunited. We are definitely related and my genealogy program determine that we are 3rd Cousins, once removed which make your Dad and I 3rd Cousins. Let me know if you want me to send you a pdf of the Relationship Chart.
Anyways, in looking at your tree it certainly aligns with mine back to Thomas Hunter (b1816) but does depart from there. I have Thomas being born in Penpont and have traced his line back to a James Hunter also of Penpont (b1715). This leads to the question of information sources so I'll recheck mine and let you know so hopefully we can resolve this discrepancy.
I'm not sure about putting my tree on Genes Reunited just from am annual cost perspective but will be happy to send you a Gedcom or other file version if you wish.
