Hello. I am the great grand-daughter of William D. McLean. Yes, he did pass away in Murillo, near Thunder Bay, ON, where I currently reside. He was born in Glengarry, Ontario, Canada on May 29, 1852. I wish I knew where his father came from in Scotland. William was a qualified teacher, but held 15-20 different jobs in his lifetime according to my mother, so he may have been the storekeeper/postmaster in Riceville. He moved a lot and owned property in Murillo, ON. There is a street named after him there to this day.
Alexander McLean's residence in Alhambra, CA was listed as 414 and 416 West Grand Ave. in 1910. In 1905, it was 240 N. Wilson St. (which became Atlantic Ave. in 1930). The residence, Diamond Castle, was built by the carpenter, Alexander McLean. You can see pictures of it on the Internet. A miniature, "pygmy castle" was also a major tourist attraction and was featured on postcards.
A street in Alhambra (McLean Ave.) and one in Murillo (McLean St.) were named after him
His wife was Rachel Esther Rees, not Reece. She was born in McGillivray, North Middlesex County, Ontario on May 15, 1868. She was a photographer/calendar/poster girl and her mother was from Wales. She had dark brown curly hair and blue eyes and was married at the age of 17 to William on Oct. 8, 1885 in Paisley, Bruce, Ontario, Canada. They then emigrated to San Gabriel, Los Angeles, California in 1902. She passed away in 1937 in Thunder Bay, ON. They had 8 children. I can name them if you'd like.
I hope this helps.
