Scottish; Murdo and Murdoch are Anglicized spellings of the Gaelic namesMuireadhach/Murchadh derived from Gaelic "sea".
Murdo is a popular name in the Scottish highlands from whence it has spread to many other English-speaking countries with a strong Scottish background, especially New Zealand.
In the 1841 Census of Aberdeenshire the variant Murdoch is more frequent than Murdo which is very rare in that record. |
