The Boyle in the 1881 census is not my one, my William Boyles married a Margaret from Ramsey,then moved to Cumberland,it shows two sons William aged 11 and I thought it said Coward, but as you say it could be Edward aged 10yrs,and Margaret as 8yrs, she married Benjamin Quayle in Workingtong Cumberland in 1903.
What wanted was what was Mother Margarets Maiden name, she was born about 1854 in Ramsey what part I dont know.
I can!t make out the county in Ireland where William was born in 1855.
I hope Ihave made it a little more clearer,
My apologies if I have mislead you.
