I searched the Irish Family History Foundation's database. It contains 11,500,000 surviving rcds for abt 60% of Irish counties. Co. Kildare is in it.
For James Forden (+variants), I found 1 M rcd in 1834 for the parish of Monasterevin. For Mary Murphy, I found a matching M rcd, same yr, same parish. These are likely your ancestors. A view of the detailed rcds MAY show the names of the parents of both parties and sometimes other info.
