Ballingarrane Walsh & Doyle families

My 2nd g-grandfather, Patrick Walsh (1821-1890) emigrated from Ballingarrane, Cloyne to St. Louis, Missouri with his brother Maurice (1819-1878). Thanks to marriage records from the Archdiocese of St. Louis, I know that Patrick & Maurice's parents were James Walsh & Margaret Doyle.

I have found great information about the Walsh family in the available Irish records, but still seek a marriage record for James & Margaret, and/or other evidence that could lead me to the right Doyle family. The first child of James & Margaret for whom I found a record (Baptismal) was John Walsh, b. 1810 in Ballingarrane.

Thank you in advance,
