Have you checked that your Tynan are from Kings?
I have several Hanrahans who settled in Boston Mass US and both mothers were Tynans. They were all from Urlingford, Co Kilkenny, Ireland. I also believe Lott Tynan to be my Lott Hanrahan's cousin as I think his father-in-law was another Lott Tynan.
My Hanrahan's mainly settled in Tauton, Mass.
Do you think we have a connection?
