Glenda got some positive results in matches to some of the other Vosper Cousins who have DNA tested. I've documented the results below.
Given that our common ancestor is about 10 generations back, it would be kind of miraculous to find matching segments – but I did find some! They are small segments, which are often ignored by genetic genealogists as being IBS – identical by state. However, we have found the very same segments among different family members, showing they are IBD – identical by descent. Here are the results of the comparisons:
Glenda doesn't match me:
She does match my brother:
Comparing Kit M522600 (*Bennett descended from Willem Adrianse) and M590264 (*Glenda GM)
Minimum threshold size to be included in total = 500 SNPs
Mismatch-bunching Limit = 250 SNPs
Minimum segment cM to be included in total = 2.0 cM
Chr | Start Location | End Location | Centimorgans (cM) | SNPs |

11 | 85,055,685 | 92,304,523 | 4.3 | 1,260 |
Largest segment = 4.3 cM

AND my other brother:

11 | 85,522,134 | 92,304,523 | 4.2 | 1,187 |
Largest segment = 4.2 cM
Total of segments > 2 cM = 11.1 cM
3 matching segments

She does not match cousin James Vosper:
Nor match Cousin Paula:
But Glenda does match Cousin Lesley Dawson:
Comparing Kit A065127 (*Geneseeker) and M590264 (*Glenda GM)
Minimum threshold size to be included in total = 500 SNPs

5 | 82,828,381 | 92,070,432 | 6.6 | 615 |
Largest segment = 6.6 cM
Total of segments > 2 cM = 6.6 cM
1 matching segments

No matches for these cousins:
But, there is a match to Sheila Stevens:
Comparing Kit A898607 (Sheila Stevens) and M590264 (*Glenda GM)
Minimum threshold size to be included in total = 500 SNPs
Mismatch-bunching Limit = 250 SNPs
Minimum segment cM to be included in total = 2.0 cM
Chr | Start Location | End Location | Centimorgans (cM) | SNPs |
11 | 81,942,795 | 87,271,049 | 3.8 | 538 |
Largest segment = 3.8 cM
Total of segments > 2 cM = 3.8 cM

There is also a match to Cousin Yvonne:
Comparing Kit A966132 (Aus Vosper) and M590264 (*Glenda GM)
Minimum threshold size to be included in total = 500 SNPs
Mismatch-bunching Limit = 250 SNPs
Minimum segment cM to be included in total = 2.0 cM
Chr | Start Location | End Location | Centimorgans (cM) | SNPs |
17 | 38,025,923 | 44,193,736 | 3.4 | 533 |
Largest segment = 3.4 cM
Total of segments > 2 cM = 3.4 cM
1 matching segments
293719 SNPs used for this comparison.
I've added this to my program for tracking DNA, and we end up with a genome map for my brother Robert that looks like this:
And for my brother Tom that looks like this:
Cousin Teri
