Comparison with tests by Oxford geneticist Bryan Sykes shows that we are related to a majority of Sikes in the U.K. including Bryan and Sir Richard, former chairman of GlaxoSmithKline.

 The number in (#) is the number of Sykes from a test group of 48 English Sykes' tested by Bryan Sykes with that DYS#.
 In 1999, Bryan Sykes, the Oxford geneticist and author, tested 48 Sykes' in West Yorkshire, Lancashire and Cheshire counties in England.
He talked about his conclusions in a 2000 article in The American Society of Human Genetics and a 2001 BBC radio special.
See Sykes Surname Origins for more information.
Bryan determined that most of the Sikes came from a common ancestor. The 50% of Sykes' who's Y chromosome resembled the normal variation of the general population can be explained by non-paternity events (name change, adoption,...) over the last 22 or more generations.
Other test results of mainly individuals without group matches are listed at the Sikes / Sykes DNA Project.
The top line in the chart represent results from one of Alvin's grandchildren. They confirm Alvin is related to Richard and also the largest family of Sykes in England, including Bryan Sykes and Sir Richard, retired chairman of GlaxoSmithKline and most likely to William del Sykes who farmed near Flockton, Yorkshire, England around 1280.
Many, probably a majority, of Sikes/Sykes in the U.S. are descended from other Sikes/Sykes immigrants who settled in the southern U.S. (NC, VA) and they are not directly related to us.
There are still three of the markers in the 25 marker DNA test for our family which have mutated thru the generations, so we need more tests from other lines to determine what Richards true values are for these and we are running out of volunteers. Several lines, like ours have daughtered out.
Our result for marker DYS392, 14 repeats, is consistent with the other test from our 7th great grandfather, Increase Sikes', descendants, while descendants of his brother, Victory, all have a 15 for this marker. So, there is a high probability that the mutation occurred with Victory, Increase or Nathaniel, our 6th great grandfather.
Marker DYS439 has different values for descendants of both Increase and Victory There are two 12's, one 13, & three 14's, so there appears to be the same mutation in multiple places.
Ann Turner, co-author of "Trace Your Roots with DNA: Use Your DNA to Complete Your Family Tree:" commented on our DYS439 results as follows:
"I'd guess at 14 for the ancestral value. It occurs in at least one line of descent from each son of Richard. But that would mean that a change from 14 to 12 occurred independently in two different lines, and a two-step difference is a little harder to swallow for parallel mutations. "
Our line and the Victory, Samuel line seem to have different mutations in 464d.
We may have to dig up some ancestors and try to extract DNA from their bones to resolve it :-) [no one has actually suggested this]. This is very difficult (Bryan Sykes research in this are is what got him started by analyzing cave man remains). Damp acidic soil in the northeast U.S. causes most remains including bones to be reduced to dark soil stains after 100 yrs.
We are also of Haplogroup R1b1. Anthropologists break down the Y-chromosome into branches called Haplogroups or clades, which distinguish major branches of Homo Sapiens. Haplogroup R1b1 is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago.
See: ycc.biosci.arizona.edu/nomenclature_system/summary.html for a report by the Y-Chromosome Consortium (YCC).
Allelle - The number of repeats of a sequence in a marker. DYS - DNA Y-chromosome Segment - markers are assigned DYS numbers. Haplo - Haplogroup Identifies the person's major population group and provides information about the ancient origin. R1b1 is the most common haplogroup in European populations. Marker - Repeated base-pair sequences (2-5 base-pairs) at specific locations along the Y chromosome.
