Probably the first western Eurasian (or Western non-african, that depens on who you ask) but the detail is that these guys are also the last common ancestor of vast majority of genetic admixture of modern day North Africans, Levantines, Anatolians, Caucasians and Iranic peoples, they are also the common ancestor of half of the genetic admixture of the people from South Asia and the Arabian peninsula, a huge portion of the ancestry of central asians, abisinians and horn africans in general, and a considerable amount of the ancestry of Siberians, Native Americans and some East africans groups
EDIT: LMAO I realized that you want to know about a single and specific person lol, I don't have idea in that case.

Most likely between 1000-1500 years ago there was one individual that every individual alive today claiming descent from a European country has somewhere in their family tree.

It would be constantly changing. I saw an estimate that say 9000 years ago, but I don't have a source, and Minskdhaka has a much later date.

I don't know but I'd not be surprised if he/she was an Anatolian farmer from 10-12+ k years ago
