I have listed in a Parish register From Kilmurry-Ibrickane, Co. Clare for the baptisms of my McKnight ancestors the following people named Lynch:
Sp. for James Mc Knight-son of Timothy&Bridget(Nugent)McK Mike Lynch & Julia McGuiness2/25/1866
Sp. for Timothy(Thady)McKnight-same parents John & Mary Lynch 1870@
From what I understand sponsors were usually relatives, or at least close neighbours. The other sponsors listed were James Frawley, Kate Donnelan, MArgaret Blake,Mary Kelley, & Ellen Kelley. Wonder did Mary Kelley later become Mary Lynch? Thought this might be of use to someone doing research on Lynches.
