Murray/Brady families in Ireland- Maybe Cork and Cavan Counties

[I4Favre]

I am looking for information on my  great grandparents families in Ireland,  Owen Murray born about 1835 in Ireland and  in Wisconsin  he married Mary Brady born 1843 and her parents were Michael Brady and Johanna O'Connell in County Cavan.

I have found these siblings for him:
Margaret Murray born about 1825/Married Thomas Trainor
Patrick Murray about 1833 in Ireland
Terry Murray born 1856

 These Murray's settled in Wisconsin.
Any information on these people would be greatly appreciated. Thanks

www.nationalarchives.ie - 1841 census in Cavan several Brady families. You would have to rely on Baptism records as Civil registration wasnt introduced in Ireland until 1864.
Do you have a marriage record for Owen & Mary as it may have their fathers names.
Also numerous records for Brady in 1821 census in Cavan

I have the marriage record, but no parents listed on there. I did find Oaens siblings by accident this past year, but no other clues to help me.
Thanks for your response.
