This study is the result of a forty-five-year-old brick wall in my family history, culminating in an effort to find and record all references to the names Tilliduff (my great-grandmother was Eliza Tilliduff) and Tullideph and thirty (to date) other spellings of the name. The study is registered with The Guild of One-Name Studies, who are hosting this site. If you are connected to the Tilliduff or Tullideph families and would like to contact me please do so through my Guild profile page.
While trying to complete my own family tree I have also been attempting to answer the following questions: Where did the Tilliduff name come from? How many Tilliduffs are there now? How many were there? Where are, and were, they? How many different spellings of the name are there? And are they all related?
The name comes from the former barony of Tillydaff to the north-west of Aberdeen, Scotland, in Midmar (not to be confused with Tillyduff, mentioned in place-names around St. Combs and Crimond further to the north-east). The name is Celtic, meaning “hill of the oxen”. The old barony comprised the areas of Orchardtown, Rothmaise, Ranieston and Logierieve in addition to Tillydaff. The Tillydaffs “of that ilk” lived at Orchardtown, but any sign of a house had disappeared by the 19th century.
The direct line died out in 1628 with the death of the last of the Tillydaffs of that ilk, Marjory Tullydaff, who had married William Seton of Disblair, and the lands of Tillydaff were inherited by William Seton her son. However, by then there were members of the family in Fife who were the ones to carry on the name until it reached England in the late 18th century with the arrival in London of my five-times great grandfather Robert Tullideph.
In all I have 211 names of people born with the name (and 30 different spellings, although only two which became the standard form – Tullideph and Tilliduff) dating from the earliest mention in 1317. In fifty per cent of the names I have proved relationship with the records available and formed a tree dating from 16th century, while in other cases, mainly in the 15th – 16th century records, I have linked parents to children but am unable to connect them further. However, in view of the restricted locations in which the family is to be found I believe them all to stem from the same family.
The name Tullideph as a surname was extinct by the end of the 18th century, the son Robert of the above-mentioned Robert Tullideph having been recorded as Tillyduff in London on the births of his children, with subsequent generations being Tilliduff. By the time of the 1881 census there were just 16 Tilliduffs recorded, all of them in Kent and London. (Two were spelled “Tiliduff” and one recorded as Henry T. Duff). The name Tilliduff is still in existence in South Africa with just one family carrying the name. Tullideph is still being carried down some lines as a middle name, (one line of which is descended from David Tullideph’s daughter Ann, b. 1736, who married William Procter, two from Thomas’s daughter Mary, 1741 – 1785, who married Thomas Bisset, and another from Walter’s daughter Charlotte, 1736 – 1810, who married John Ogilvy, 5th Baronet of Inverquharity. )
I have some records still to add – come back later for a second look and they might be there!
