The known surnames of persons in this group to 5th cousin level are; Davis, Barns (Barnes), Gatrell, & Preston. There are a number of gaps in our knowledge of ancestors at this level. The link to the descendant chart related to these matches is Davis.
Three matches are through John Davis' son John, 1803-1890 and his son John, 1832-1909. These are to Lesley Davis, Averil Jane Davis, (who has a ThruLines link on Ancestry) and very recently to Gareth Anthony Adams. There is another match to Caroline Miller shared by Averil and Gareth but her connection is to be worked out.
The second line from John is through his daugher Emmeline, 1811-1882 through Elizabeth Spurrier to Edward Henry Collington of Poole, 1870-1940, to Lesley Barbara Collington, his granddaughter. Another match on this line comes from Edward's brother Samuel George Collington to his great-granddaughter Tracy Brown, whose son matches at 9cM on 1 segment.
The third line with 4 matches is through John's son James, 1807-1885, to his daughter (and my great-grandmother) Sarah Ann Davis, 1842-1926. Her eldest son, Tom Galton, 1875-1948 leads to my mother Edith Elsie Galton to which mine, my children and my nieces all match. Tom's eldest son Harry, 1877-1828, leads to Corinne J Thompson, via her mother Maureen Gibbs, 1936-2016.
These matches are in large part due to the good on-line trees for this side of the family in spite of the low level of cM in some cases.
No identified connections have appeared in any of the cluster analyses done so far. However, as with the Galtons, there are strong indications of connections from Dorset and Hampshire matches to Newfoundland including the surnames of Anstey, Davis, Galton, Verge and Pelley. It seems most likely that this connection is to the Anstey family of which there is a One-Name study. 'Our' branch is from those of Poole though the family is ancient and comes from Anstey in Hertfordshire where a descendant of a Norman family was granted land. It has its own web site here, and there is a book that describes the studies of which I have a copy.
