The Henwood and the Robinson line in our family are both in dna language listed as R1b1b2 haplogroups. In finding information about the dna of Henwood, the paragraph below is important. I didn't know it could be called ht15. The R1b1b2 of my mother's father (Robinson) is different by being much older than this line and coming from the East. I find this out by the number on DYS on the Robinson line being 12. The Henwood's DYS 393 is 13.

The main European groups consisting of R1b1b2 (ht15) which the Henwood line is included are probably less than 6 thousand years old although some still argue for a pre Ice Age existence.
