McKenna family history

Dear sir - I live in Queensland, Australia, and I am researching family McKenna/Traynor. Official census records 1881 show the family resided in Tow Law, Durham England, but were born in Ireland (County Meath) 1816/1817. Details are: James McKenna married to Mary Traynor (? 1849). Children: Patrick McKenna (1850 - ?); John McKenna (1852 - ?); James McKenna (1854 - ?); Matthew McKenna (1857 - ?); Edward McKenna (1859 - ?). Whilst this information is limited, I would appreciate any correspondence which may assist me in researching my family. Correspondence to bclaireburrows@aanet.com.au. Yours, Beverley Burrows, Australia.
