Margaret Sullivan : Short Biography

Margaret married James Ryan (Shanvoher) and was the Mother to Ellen Ryan (may17th, 1870) I am very interested in these Ryans and Sullivan's as Ellen's husband died at 28 leaving her to bring up 2children. He was buried with his Mother and when Ellen died I believe she was buried in Newberry (cannot find anything) or I cannot find any reference to either parents or Ellen in 1901 census. She was living in Gurrane, Bianteer in 1911. Did Ellen have siblings? Where was her Mother from (I believe Father pre decreased Mother) She is a mystery really. Thanks for any help to give me a lead.
