I am looking at a book " MacAskill, Seascapes and Sailing Ships", with many of his great pictures. ( My favorite is " Grey dawn.) The book says he was born in Cape Breton, N.S. in 1893 and died 25 Jan 1956.He married Elda Abriel. The photo " Grey Dawn" titled from the poem by Masefield " I must go down to the Sea again." He and Masefield were friends.
Unfortunately, I still have not connected him to my MacAskills, and the Giant MacAskill.
