Unfortunately there's not much about Larkfield in ''Crumlin, and the way it was'' by Finola Watchorn, just a few references to the townland and this short passage on Larkfield Flour Mills:
''Larkfield Mills was situated behind the present Sundrive Shopping Centre. Around the middle of the last century [i.e. the 19th century], it was run by a Francis Tuite.
It was later owned by Count Plunket, who's son, Joseph Mary Plunkett was executed at Arbour Hill [?] in1916. Kimmage was a republican stronghold at that time and Larkfield Mill was used as a training ground for the Republican forces before 1916. There was also a shooting range at this mill and it was said that Michael Collins trained here''.
There isn't an index in this otherwise fine local history, published in 1985, but I've flicked through it and I think that's the only reference.
