Patrick Corbitt/Corbett, 1805-1810 of Ireland and Nicholas Co, VA/WV

Looking for info on Patrick Corbitt who was born in Ireland bet 1805 and 1810. He died in Nicolas Co., WV and was married to Susan Neff.
Based on marriage certificate and death record I know his birth and death places. His marriage certificate (to Susan Neff) states that he was widowed.I think his father's name was O James Corbitt and mother's name was Catherine.

Does anyone know:
1) the name of his first wife and where there any children from this marriage?
2) what county in Ireland was born?
3) name of his parents?
4) were there any siblings?
5) when did he leave Ireland and arrive in USA?
