Welcome to Ireland Reaching Out!
I located a transcription of the marriage record on the subscription site Roots Ireland.
Date of Marriage:25-Nov-1823
Parish / District:MACROOM
County:Co. Cork Husband:DenisLynch
The Macroom baptismal records start September 28 1805. I did not locate a Denis Lynch or a Johanna Kelleher baptismal record in the available Macroom records and likely they were baptized prior to September 28, 1805.
