Wentworth Odiarne Cavenagh (1856 – 1935), a first cousin of my great grandmother Kathleen Cudmore née Cavenagh (1874 – 1951), was the son of Sir Orfeur Cavenagh (1820 – 1891). He was interested in family history and heraldry and he spent a considerable amount of time researching Cavenagh family history in the Irish National Archives.

W. O. Cavenagh

W.O. Cavenagh presented his research to the Office of Arms in Ireland and the original manuscript and typescript (about 175 pages) is held by the Genealogical Department, Dublin, Ireland; it is much used by Cavenagh family historians. His research has also been microfilmed by FamilySearch.

Other family history documents, including many fine heraldic illustrations, are in the possession of his grand-daughter.

Some of the family history recorded by W.O. Cavenagh

Some of his research on the Cavenaghs of Kildare has been transcribed by another cousin, who has given me permission to share it.
