I did some researching last night. My husband's great-grandmother was Ellen CASEY. She married Patrick DEVINE in 1871. Alas no Civil Registration has been found which would have named the father at least. I had two possible birth years for Ellen based on the 1901 and 1911 census. The 1911 census was 1841 for Ellen. I found one match for that year. It was the only close hit. Ellen CASEY dau. of John CASEY and Mary DONELON. Jan 20, 1841. The parish was Killashee. I felt I had seen the name DONELAN. Well in the Valuations (of Ballymahon) when Ellen leaves or dies the person who lived in the place after her was a James DONELAN. This was in Ballymahon. I then bought the record of marriage for John CASEY and Mary DONELAN. Also the parish of Killashee. 1835. No parents listed. Witnesses John Egar and Mary Flynn. When the last daughter Norah DEVINE came to American she said her relative in Ireland was a Mrs. DUGGAN in Little Water Street Longford. So, using census which had a John DUGGAN and wife Winifred. I found she was Winifred CASEY. Her father it turns out was Peter CASEY. In 1901 a Winifred Casey and in anther place a Peter Casey list Roscommon as their birthplace. In 1911 Winifred DUGGAN says she was b. in Longford. Searching the Longford IFHF site I find virtually no Winifred Caseys being baptised. When I try Roscommon I am hit was bunches of Winifred Caseys in the time frame of her birth (ca. 1875). So, in theory Ellen Casey is the dau of John Casey and Mary Donelon. Her brother is Peter Casey who has a child Winifred. Can anyone add on to this? Thanks, Christina
