Esslemont is in the parish of Ellon, a short distance west of the town of Ellon. See

In 1861 Thurlaw Fraser, 34 was a journeyman miller there at Little Mill, and his wife was living with her parents in the parish of Tyrie. See Reply #53 above.
Ten years later, in 1871, Thirlow Fraser, 44, journeyman miller, is in 54 Low Street, New Pitsligo, parish of Tyrie, with wife Jane Cowie and five children. See Reply #54 above.
These are two different places, so Thirlow must have moved from Ellon to Tyrie between 1861 and 1871. This is quite normal. The term 'journeyman' has nothing to do with travelling. It is from the French 'journée' which means a day, and a journeyman is a skilled man who has completed an apprenticeship, and is working as an employee for a master, originally paid by the day.
Another ten years later, Thurlow, aged 54, meal miller, is at Denburn Mills, parish of Tyrie. You can view the LDS transcription of the 1881 census at
www.scotlandspeople.gov.uk free of charge. So he has presumably taken on his own mill instead of being employed by someone else.
So there is no need for any confusion. He simply moved jobs from Ellon to Tyrie.
