Haplogroup Hb3

[Kiwi]

Any idea where this offshoot is most prominant?
What is known about Hb3?
My paper trail is only back to a woman born about 1810, married most likely in Ireland, her surname was Paterson, no idea who her mother was, she died in Kilrea 1881, was lucky that sevearl daughters died in countries where the death certificates names the mother's parents, sure wish Ireland had done that.
