I think the Rushen Mcylrea is not in the direct Fildraw line - his dau Jony being too sick to act is a red herring as if she was deaf + dumb and he was the Thomas of Ballaquaile then he would not have appointed her as jt admx - the sibs don't seem to match up either - don't forget there was a Ballasalla Mcylrea family John + Elinor, son john tailor in Dublin who sells house + garden in Ballasalla to Wm Stole in 1735 after death of his mother.

I think we are both missing two key wills Jony mal 1741 + thomas 1712 - I emptied my cache of mylrea Malew wills online earlier - just working thro the morts + sales which are making the Lib Mon rent rolls of 1740 (online), 1750 + 1760 make more sense
Charles m Margt (name unkown) - eldest son Charles m Mary Bridson - he mortgaged + sold quite a bit
his son was Charles I think but not got down that far
