At most, I would only be connected to the Marriotts via my maternal line. My mtDNA HVR1+HVR2 combination is rare enough that anyone with it deserves scrutiny. I found a rare match on the SMGF website, and I traced the short tree provided back to Jamestown, Virginia and Alice Powell, born about 1622. She had two daughters, Elizabeth and Alice Warren. Alice Warren married Matthias Marriott. I'm probably not related at all, or maybe to the other (Elizabeth) branch. I am clueless at this point, with only that rare mtDNA match to keep my interest up.
My mother, many years ago, made the remark that she had Marriott relatives. That was when she, my step dad and I were having lunch at a Marriott hotel (Miami). It may have been a jest, but then maybe she knew something. However, if this project would like to have my mtDNA information; or even have me join, then let me know.
