There's a marriage of an Edward McCabe and Margaret Byrne listed in Hacketstown RC parish on the 20th September 1841.
see : Hacketstown register 1841/42 The marriage entry is included in the top section of the left page.
The Catholic Parish of Hacketstown also covered parts of county Co. Wicklow.
two additional children to Edward and Margaret:
Margaret bapt. 11 August 1851
Susan bapt. 19th November 1854
both in Hacketstown RC parish. I didn't spot any earlier children baptised in Hacketstown or any of the nearby parishes, i.e. between 1841 and 1848.
