any information regarding his background?
According to D.E.R. Watt, Walter might have two brothers- John and William. He might also have been connected to Margaret de Abernethy.
Walter de Coventre
D. E. R. Watt has suggested that the medieval settlement of "Coventre" or "Covintrie" near Abernethy in the diocese of Dunblane was the origin of the name.

There is no direct evidence of de Coventre's family, but two other men bearing the name "de Coventre" are known to have been active during Walter's lifetime. A "John de Coventre" is found registered as a student at the University of Paris on 21 January 1331. Before December 1341, when he resigned, John de Coventre held the parish church of Inverarity, Angus, in the diocese of St Andrews. On 7 December 1345, a William de Coventre, also from the diocese of Dunblane, held a canonry and prebends (a cathedral priesthood with stipends) in the diocese of Ross and the Collegiate Church of Abernethy, when he was granted the church of Inverarity that had previously been held by John de Coventre. William thus appears to have succeeded John (and later Walter succeeded William) to all of these benefices.
