The Carroll Y-DNA chart for FTDNA is at the following link.https://www.familytreedna.com/public/carroll/default.aspx?se...
This includes a 67 marker kit for someone claiming to be a Demse Carroll descendant (kit number 55631). Unfortunately, there's no way to check the kit owner's line of descent.
If this kit owner does descend from Demse Carroll, he is in the Niall of the Nine Hostages group and not connected to Charles Carroll, the signer.
A 37 marker or 67 marker kit is sufficient for identifying the haplogroup, but not for confirming a close connection. As an example, I am also in the Niall of the Nine Hostages group, but my common ancestor with kit owner 55631 occurred somewhat earlier than Colonial America.
