Hollow DNA Project, Results update Mar. 2017

The results for ten tests are now available.
They are divided into three different groups according to their haplogroup. You may notice the naming of the haplogroups have changed. They are still the same haplogroups, it is just the naming convention has changed. In the first haplogroup the results of the seven people tested (listed 1 - 7) have almost the same haplotype. Interestingly their male lines go back to three different Holla/Hollow men.

The fact that the haplotypes are almost identical indicates these three Holla/Hollow lines (John Holla and the two William Hollows) are all related. This provides us with a couple of breakthroughs.

  1. Although we have been unable to link John Holla b c1670 to William Hollow b c1660 using the conventional family history sources, their Y-DNA results indicate they had a common ancestor.
  2. William Hollow bc1780 must also share the same ancestry because his line has the same Y-DNA result.

A look at the results shows that all seven people in Genetic Group 001 have almost identical haplotypes. Each of them has one or two differences. This is not unusual for pedigrees that cover over 400 years. A difference in the value of one or two sites is pretty regular in such pedigrees.

When I look more closely at the male descendant lines they show that the people who have tested are not closely related. The closest relationship is third cousins,the rest are even further apart.

What do these results tell us?

The consistency of the results means we can confidently say what the marker haplotype or identifying haplotype of the Holla/Hollow family from Zennor is. Any male Hollow whose tests show this same haplotype, give or take a couple of differences, can be confident their ancestry goes back to a Holla ancestor whether they can trace the line back by available records or not.

The other two tests

Two different haplotypes have been found.

The haplotypes are so different they are given a different haplogroup. The first, shown as in Genetic Group 002, presents us with a conundrum. The haplotype is quite different to the seven in Genetic Group 001 but the family tree for this person shows a pedigree back to William Hollow and Uslea Cock. They are the same couple that gave rise to three members of Genetic Group 001.

This suggests there has been, what is called a non-paternal event. That is, somewhere in the family tree there is a male whose father was not the son of a Hollow male. This may have been due to adoption, born out of wedlock, baby mix up in care. There are a few ways this might happen. To identify where this happened in the family tree we need to closely analyse this particular family tree. The line diverges from the root family tree after three generations from William b c1660. What also might help are more tests of people on other lines that link to this divergence.

The second different haplotype has a different story.

We have one Hollow tester, Jim, in this group. There may be a non-parental event that would explain the result. The research into Jim's ancestry shows his line goes back to Ishmael Holla born 1723 in Zennor to Jane Holla b c1700. In the Zennor baptismal register Ishmael is described as a base child, that is, born out of wedlock.

There is a slim chance of finding out the father of Ismael through written records.When searching for Holla records in the Cornwall Records Office on-line catalogue I came across two references to Jane Holla. In 1723 Jane Holla of Zennor was excommunicated from the Church (children look away) for fornication. Both the references refer to this event. Now through my regular viewing of the TV program Who do you think you are? I remember that there have been similar happenings and that the official church record of this non-parental event often includes the name of the father.

I ordered copies of the two records and they came to hand. I found I had two additional problems.
A, the records are written in an old English script that is hard to decipher and
B, they are also written in Latin.

I have had a couple of people who know Latin and can read Old English script. Their analysis is that the name of the father does not seem to appear in either of these records.

So another part of the study is still a work in progress. More tests could help so if you are a Hollow male please make contact and we can work out whether a test on your Y-DNA would be helpful.

It is not all bad though!

Zennor was a small community and it is highly likely that Jane Holla belonged to the Holla or Hollow families that lived there and that we now know via DNA that they are of the same larger family. So the combination of traditional research and DNA study supports the idea that this variant haplotype is part of the Holla/Hollow famliy.
