Memorial to Bob Owen Croesor (1885-1962), the antiquarian and book-collector. Robert Owen (or 'Bob Owen Croesor' as he was better known) was a native of Llanfrothen, Merionethshire. After leaving school he was employed as a farm worker and shepherd, but later worked as a clerk at the Parc and Croesor slate quarry. He became a lecturer with the Workers' Educational Association (WEA) and was a popular radio broadcaster. He was particularly interested in the fields of local history and Welsh genealogy and transcribed the parish records of a number of parishes in Merionethshire, Caernarfonshire and Denbighshire. He was also an avid collector of books and manuscripts. He undertook extensive research on the history of the Welsh in America and published a number of articles on the history of Welsh homes.
