I have tested negative for i-z59, and know that I am i-z58 already. my family's subclade must be i-z138. The family name is Westbury/Westberry and also possibly Furman/Firmin before the 1600's. earliest ancestor is Moses Josiah Westberry 1772-1864. If anyone within the I-z138 could post their findings, that would help immensely! Thank you!
