Correcting my previous comment, actually WikiTree shows possible DNA matches up to 8 degrees of separation. In addition to the great widget that Kitty shared, showing all the surnames on your tree, there is this useful report which you can get for any profile on WikiTree who has had a family member tested within those 8 degrees of separation. Yours currently looks like this:
The description is:
"Here are family members that have been connected for Michelle Walls's autosomal DNA test. This includes all blood relatives within eight degrees of separation — up to sixth great-grandparents and out to third cousins.
Click ancestor and descendant icons by individuals' names in the list below to see their trees. Click a Relationship Finder icon to see their relationship to Michelle."
You get that list by looking at the DNA section on any profile where it says: DNA Tested
Michelle Walls's DNA has been tested for genealogical purposes. It may be possible to confirm family relationships by comparing test results with Michelle or other carriers of her ancestors' mitochondrial DNA. It is likely that these autosomal DNA test-takers will share DNA with Michelle:
followed by a list of names. For each names there is a hyperlink 'test details'. When you click on that link, you can see all the relatives of that person within the 8 degrees of separation.
Your list is short, because your twig is still growing. Because i have been gradually growing my tree here for about a year and also many of my ancestors were here already, my list has over 400 names on it. The most useful part is that i had never before heard of many of those people and lots of them are still living (yellow button), so DNA work can happen.
I think that is similar to what you were looking for when you originally asked your question. If you can grow your twig just a few more generations, then we can all help you more. Your parents profiles are private so i can't see dates or locations, so i can't help you grow your twig. But if you get into a timeframe where you can have public profiles on your ancestors, you may find that they already connect up to the big tree or someone can help you get a few more generations back.
