Just wanted to leave this here for everyone, in case it helps.
It's an analysis of the Ross Y-DNA Project at Family Tree DNA.

Several descendants of Hugh Ross, "The Immigrant" have tested & they fall into Matched Group 42.
One Isaac Ross, Sr. descendant has tested & he falls into Matched Group 12 along with several descendants of George Ross of Elizabethtown, NJ, Scottish Prisoner of War.

One kit lists Rev. George Aeneas Ross, M.A. as an ancestor. I was not able to verify the pedigree they provided. There don't seem to be any conclusive sources. Either way, they are not a match to either of the groups listed above.
There is another interesting group, Matched Group 53. It contains descendants of the Roses of Castle Kilravock in the Scottish Highlands. There are both Rosses & Roses in this group. It is unclear, though, exactly how they connect.
There seems to be an assumption, though, that this demonstrates a relationship between Clan Ross & Clan Rose and that any descendants of the Rosses of Balblair would fall into this group.
None of the pedigrees submitted by participants in this group demonstrate a connection to these Rosses, though.
So, basically, there is a very impressive number of participants in the Ross & Rose projects, but there is still no conclusive connection to these Ross Lairds. Or at least not one that I could flesh out based on the information provided publicly.
Would love to hear if anyone has any more information on any of these groups.
