Grady Family

Hello. I'm interested in finding more information about Daniel Grady father of John Grady (John's dob 1828 ish). John was living in Manchester, England in 1851 and I do know he married Mary Waldron in 1855. On the marriage certificate, Daniel Grady was deceased, and occupation was a labourer. I have found 3 baptism records for John that could be of interest, 2 at St Michaels, Limerick, and 1 at Ballybricken. I would love for some help with this. Any help would be greatly appreciated. Thank you.
