Yes, new to this but using med skills it appears so be a "link" or maybe the 335 is an area code but if the person is going through all the trouble to link 335 DNA then I would follow the link(s) to some word or conclusion( rabbit hole).
Possible thoughts on familial DNA? Most the royals are all related and there IS an oligarchy in the USA. I'm not big on genetics but again why give a DNA hint if just superficial or maybe an area code?
