You had better take this up with a few projects. A Baron of Ossory would be somebody prominent in Irish history, so they would get Protected Profile status in Irish Roots. A Baron would also qualify for European Nobility status, so Euroaristo would be interested in this profile.
If you go to those projects and ask for help, you will get plenty of assistance, as I am sure much interest will develop in this profile. Good luck with it, as I cannot help you more.
