Thank you for your advise Francisco. I did look at the 1881 census and found the correct family. I tried the 1891 as well with no luck. I did discover that Murdoch and William are one and the same....There was a registered correction entry on SP website indicating the name change. I also found a marriage for Murdina. She married a Robert Taylor but died about a year after the marriage. There were no children with the union. Robert re-married a few years later to a woman by the name of Barbara MacKenzie and thet had a family. Can't seem to find marriage info on the remaining MacLean's as yet.
