To actually clarify the 1881. census.
56 Stonelaw Street, Rutherglen.
David Mulholland, Head, Farm Servant, M. age 26 years, M. born Ritherglen,
Sarah, Mulholland, Wife, M. age 28 years, F. born Ireland,
Jane Mulholland, Daur, age 4 years, F. born Rutherglen,
Maggie Mulholland, Daur, age 1 years, F. born Rutherglen.
Then 56 Stonelaw Street, Rutherglen,
Marjory Mulholland, Head, Outdoor Worker, W. age 61 years, F. born Ireland.
This from the 1881 census disc, from Family Search.
However on Scotlandspeople, 1881 census all these Mulholland's, are in the same household.
So by that reckoning David Mulholland, on this census must surely be Marjory's, son David, born 1856. Rutherglen.
