The pictures that we have of Culdee life in the 12th century vary considerably. The chief houses in Scotland were at St Andrews, Scone, Dunkeld, Lochleven, Monymusk in Aberdeenshire, Abernethy and Brechin. Each was an independent establishment controlled entirely by its own abbot and apparently divided into two sections, one priestly and the other lay. Culdee priests were allowed to marry. At St Andrews about the year 1100, there were thirteen Culdees holding office by hereditary tenure, some apparently paying more regard to their own prosperity than to the services of the church or the needs of the populace. At Loch Leven, there is no trace of such partial independence.
