According to Catholic Online, Saint Donald (eighth century) was a married man whose wife bore him nine daughters. After his wife died, they formed a religious community of sorts under his direction. The daughters later joined a monastery founded by St. Brigid. Donald was a common name in Scotland, not because of Saint Donald but because of the many members of the Clan of Donald. Nonetheless he was known for his holiness. His feast day is July 15.
My husband Don is Irish, not Scottish (although both are Celtic) and he has six sons. But he did lose his first wife, Deborah Evans, to cancer at the age of 31, and he is a spiritual person whose faith has always been important to him.
