I submitted DNA samples to both the Family Tree DNA (FTDNA) and the Sorenson (SMGF) organizations for analysis. The FTDNA results were obtained first and they reported that I had relationships with several people in their database. Armed with the FTDNA results I was able to search the SMGF Y-database to find the results of my analysis with SMGF.
I then used the combined 25-marker FTDNA analysis and the 36-marker SMGF analysis of my DNA samples, as are entered on the first row of the following chart, to search for DNA results of other Marsh families worldwide within the SMGF Y-database. The printout was for 14 Marsh participants broken down as follows:England-7, USA-4, Canada-2, Ireland-1. Of the England participants only two, myself and one other had known roots in Kent In addition to the SMGF participants I was aware of some FTDNA participants. The chart is in two sections, one for results of Marsh families with results close to mine and the second for results for Kent Marsh families with results very much different from mine. Since A6, A10, A14, A111, A58, A70, A63 and A66 results are relatively close to mine they can be considered as having common male ancestors with me at some points on my male lineage, this has been proven to be correct for A10 and A66.
A10 results are an exact match with mine on 25 FTDNA markers, which means there have been no mutations over fourteen generations - seven back from me to our common ancestor and seven forward from the common ancestor down to A10. The common ancestor was indicated by documentation, but not proven without a doubt until the DNA testing.
A66 results differ from mine on just one marker of 25. The apparent (not proven without a doubt) paper trail leads to the same common ancestor as that for A10 and me, A2. This suggests that a mutation occurred somewhere in the line from Henry Marsh, 1758 (see comparative tree chart below) down to A66. DNA analyses from more descendants of Henry would be useful in determining where the mutation occurred.
The result for Kent A6 was reported by FTDNA as a 25-marker four-step mutation from that given for me; three markers having different scores. However, When A6 results from Sorenson were added to the FTDNA, additional differences were found. This illustrates the desirability for analyses to be done for as many markers as possible.
A14 results are for a Marsh family in Ohio, USA, A58 and A70 for a family of Maryland and Kentucky and A63 for a family of Tennessee and Virginia. Various researchers have traced A14,A58,and A70 to a common ancestor in a John Marsh who married an Ann(Anabel) King. However, assuming the paper work to be correct, the DNA results would appear to show that mutations in two markers occured in the line down from John to A14. Paper work indicates that A58 and A70 have a common ancestor in Nathaniel C Marsh 1808. However, mutations in DNA have occurred in each of the respective lines down from Nathaniel. The closeness of all the results to mine indicates that at some point there is a common ancestor, possibly in Kent. The probability of this Kent connection is increased by the most recent reults, A111, of a proven Kent line.
The second section of the chart shows FTDNA results from two Marsh Kent families both having very different results from mine and from each other, indicating that any connection between ancestors would have occurred many thousands of years ago. A3 is a very good friend of mine and we have shared research efforts for some years, initially thinking that we might come from the same Marsh line. Once the DNA results were in, we knew it would be fruitless to search for a connection through documentation research because the connection would be so far back in time. The same applies to my relationship with A4 and between A3 and A4. Thus DNA has been helpful in proving that there are several Marsh families in Kent with no close or near-distant connections.
More Male Marsh participants are needed to expand on the current findings
The results in the chart do not give any clues as to ancient
roots. This subject is tackled in pages Some

It is readily seen that some markers are common
to all records in the table . I have labelled a row 'Common' to show these.
These can be considered as part of the DNA for a founder of a small branch
in the world family tree to which all seven persons belong.
