Chromosome map update

The above is an update on my earlier Chromosome picture, but using a more comprehensive tool, thanks to Kitty Cooper's ChromosomeMapper.
The reason for this update is the small orange segment of dna on chromosome 15, a newly detected, triangulated match* between myself, two maternal aunts and Richard, my 6th cousin once removed.
I and the aunts descend from Elizabeth ALGAR and Richard PEEK, Richard descends from Elizabeth's brother Samuel ALGAR of Yealmpton, Devon.
Their parents, Samuel ALGAR & Sarah LOWRY married in 1720, at Yealmpton.

There aren't quite as many unmapped areas as all the grey indicates on the above, I've simply left off the match segments from the very close relations where there is insufficient information on matches to enable segments to be tied to specific earlier ancestors.

To identify more of the grey bits, and thus help break through some of the brick walls, I would particularly love to hear from descendants of the following of my ancestral lines who may be interested in exploring their genetic heritage, and thus help pinpoint where some of the many  matches "fit":
- William CLINTON & Jemima PARKER
- Robert TURNBULL & Eleanor SCOTT
- Andrew GRAHAM & Jane GRAHAM
- William BATY & Sarah BATY
Check out my FamilyFinder project FFLornaHen, and the FAQs about FamilyTree DNA's  FamilyFinder test, and if willing to help, please contact me (details on footer of most of my webpages)
