Hi Maureen,
The link at the bottom gives a lot of Musgrave information for Derreenasoo. In the footnotes at the bottom, it mentions the Crawfords of house number 2 in Derreenasoo, which is my grandfather's 'home place'. I believe your family married into the Crawfords that lived at house number 3, also noted. The Church of Ireland graveyard at Tumna is where our family was buried. It is not far from Derreenasoo and, presumably, there will be Musgraves there too.
My father bought the farm in the early 1980s from William Taylor of Boyle. William had bought it from the last Musgraves that lived there (I’m not sure of the date).
I now work in London, but commute back at weekends to my own farm near Boyle, Co. Roscommon,. If you were planning a visit, we would be happy to show you the old Musgrave farm and introduced you to my father, who would most likely know more. I should warn you in advance that the house was converted to a cattle shed many years ago and the farm is now planted with conifers, as my father is retired.
However, he kept the meadows and a donkey named Jenny lives a very happy life there. The house was on top of a hill and had great views of the surrounding mountains. The hill runs down to border the point where the Fiorish River joins the River Shannon and, on the other side, runs into wild turf bog with an old forest beyond. It is the scene of my childhood and has a lot of happy memories tied to it.
I hope this information is of some use.
Robert
