I actually have a Murdoch MacLean born on Skye in 1874. Seems his mother , Catherine MacLean, has no "husband" listed for both her sons. Murdoch had a son also named Murdoch in 1902. Older Murdoch died in 1940 and worked as an Electric Crane Operator.
Catherine's father was a Duncan MacLean born in 1810 but he had no sons named Murdoch. Makes me wonder where Catherine got the name from.
I am going to ask my Scottish cousins and friends about the poet Murdoch MacLean now.
