Does it mention a forename with Whyte?
For example, there was:
Alexander Whyte and Son papermill at Milngavie
Thomas Whyte and Son Muslin manufacturer, Glasgow
Robert Whyte and Sons Upholsterers and Cabinet Makers, Glasgow
John Whyte & Son, Glasgow ..... possibly connection with flour
some of the above had a different forename, depending who was head at the time.
There may have been others.
