Pitlit lists for you three possible noble families that you can visit.
The first is High Noble Lord Samuel D'iago. His family has the largest ranch estate in the nation and is the 3rd oldest noble family, dating back one thousand years. None dare typically venturing on his lands, which are to the south near the border of the hills and closest to the so called Southern Kingdom.
The second is City Noble Lord Andrew Maximillion. His family has been the lords of the city of Meldrage for more than five hundred years. His control of the city is impressive and there is little likelihood you will be threatened there. Meldrage has a diverse population of humanoids and orcs.
The third is the Landed Noble Trent Agoday. His family has been nobility for several generations. Their land is in the central plains and while they have a small territory, they have some of the finest structures in any noble land. It is centrally located, so getting to other locations will be the fastest from there.
