Not meaning to show-off, but it was very easy to find all the below info on Brennanstown and Tully by just using search engines. Maybe this will help find the Parish of Tully: "Tully Church (Cabinteely) - Church of uncertain date, but chancel dates from the 12th century. One of its crosses is engraved with a figure holding a crosier, and is said to be that of St. Brigid. Evidence suggests that Tully church had strong ties with St. Brigid's monastery in Kildare." http://www.dlrcoco.ie/antiquit.htm Also there is this: "Brennanstown Dolmen is one of six surviving in South Dublin" http://hermes.ucd.ie/gsb/about/dolmen.html and Brennanstown Riding School Ltd Hollybrook, Kilmacanque,Co Dublin Tel: +353 1 286 3778 http://www.mad-map.ie/wf/dublin/html/equestrian.html but also see below, which makes it look as though Brennanstown is on the Dublin/Wicklow border. This also has road directions to Brennanstown: Brennanstown Riding School Hollybrook Kilmacanogue Bray, County Wicklow "Brennanstown Riding School, an AIRE and British Horse Society approved riding and training establishment, is situated in the beautiful Hollybrook Demense, adjoining the magnificent Kilruddery Estate, the ancestral home of the Earl of Meath.
