It's still a townland north of the village of Enniskerry. It's not part of the Powerscourt estate as it currently exists.

However back in 18oo's things may have been different, but it may just have been a townland and not part of the estate

Trustees of Viscount Powerscourt in "Immediate lessor" column for majority of holdings in Monastery townland on Griffiths' Valuation. Some other names in the column were tenants sub-letting. It looks like Viscount Powerscourt owned most if not all of Monastery.

The Powerscourt Papers available online from the National Library don't have any references to McMullen that I can find, but there are references to Monastery (spelled Monastry in it) so maybe you could find some other family names

 i think family search have me on the wrong track they have every thing right about gggrandfather thomas him marrying in greencastle co antrim and having children there but when they say his father is called william his  syblings edward and william  and   thomas  there is christenings for edward and william but no thomas  i think thomas brothers was called danial and james  so think i am on the wrong mcmullans   the mystery goes on  regards   mike
