This is an interesting name of Medieval Scots origin and is locational from a place so called near Dingwall on the Firth of Cromarty, or from any of various other minor places named with the Gaelic element, 'Tulach', meaning a hillock. The variants are Tullo, Tullock, and Tulloh. The following examples illustrate the name development, Walter de Tulache (Forfar, 1376) Wat of Tulloch (Woodwrae 1388) David de Tolauch (Carnconame 1409) David Tullow (1506) DAvid Tullo (Hylcarny 1520) Tullocht (1600). Amongst the recorded examples in London are the marriage of Catherine Tullock and William Pritchard, June 12th 1757, at St. James, Westminster and Elisabeth Tulloch and William Boot, on 16th August 1789 at St. Leonards, Shoreditch. One John Tulloch (1823 - 1886) was principal of St. Andrews. He distinguished himself at St. Andrew's University, was assistant-minister at Dundee (1844 - 1845), appointed principal and professor of theology at St. Mary's College, St. Andrew (1854), and was appointed chaplain the Queen Victoria (1859). The first recorded spelling of the family name is shown to be that of Nicholas de Tolach, (witness), which was dated 1364 Brechin, Scotland, during the reign of King David 11 of Scotland, 1329 - 1371. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
