Looking for any family members of Philip and Bridget Coyne. Philip was born in 1866 and his wife Bridget was born in 1868. Both were born and lived in County Galway. Siblings were Bridget, born 1889, Patrick born in 1892 and Philip born in 1894..
As Philip and his sister were born after 1864 they would be civil records
This is the contact details for Galway : http://findaddress.citizensinformation.ie/service_finder/query.py?category=Civil+Registration+Offices&county=Galway&town=*
That will give their townland and then you can search for themin the 1901 census http://census.nationalarchives.ie/
A message in that parish would then get youin touch with the local people who can help
There is a record for a Philip baptised in Renvyle in1865 but as I presume you saw this and discounted it the civil records would prove your best route forward
Best of luck
Martin
