Patrick O'Hora, son of Patrick O'Hora, Tullysleva

A record exists of Patrick O'Hora, son of Pattrick O'Hara and Biddy Mangan being baptised in Backs in December 1838, Patrick snr was born in 1803 and Biddy in 1805. On Patrick' Jnr's wedding certificate, in 1867 his father was given as Patt O'Hora, Farmer, Deceased. Patrick Junior is first recorded in Rochdale/Bacup in Lancashire in 1861 English census as lodger. Patrick Junior's year of birth changes from year to year, on census forms, marriage certificate, death, in 1903. It is never 1838 but nearest is 1837. My dilemma is therefore was the Patrick O'Hora jnr the son of Patt senior and Biddy? There also exists, in the baptism records of Backs a baptism in 1834 of a Patrick, son of Patrick and Ann Priall, could this be him? Unless I can identify his correct parentage I cannot determine my Irish relatives. Patrick Jnr childrens' names, in date order were:- Ann, John, Patrick Joseph, Mary, Michael (my Gt Grandfather), Thomas, William and James. They were all born in Lancashire, England. Their surname became O'Hara in English Records. Patrick Jnr's wife maiden name was Mary Sullivan. Any insights into my Gt Gt Grandfather Patrick (Patt) jnr's life and parentage will be gratefully received
