[2][1] Although Manx had begun to disappear as a community language for most of the Isle of Man in the second half of the 19th century, it lingered on slightly longer in some more remote areas such as Cregneash.
[2] At the age of 14 Maddrell began working as a cook on a fishing boat, sailing from Port St Mary to Kinsale in Ireland and to Shetland off Scotland in search of herring.
[7] Following the death of Sage Kinvig (c. 1870–1962), Maddrell was the only remaining person who could claim to have spoken Manx Gaelic from childhood, although at the time some other people spoke it as a second language, having learned it later in life.
"[10]Maddrell appears to have enjoyed his minor celebrity status, and was very willing to teach younger language revivalists such as Leslie Quirk and Brian Stowell.
[11] Today he is remembered by an annual lecture on Celtic language survival hosted by Culture Vannin and Yn Çheshaght Ghailckagh.
