In the 16th Century, Marino Grimani was 89th Doge of Venice and started a quarrel with the Pope.

Julia's father, Gasparo (also known as Gaspar or Jasper) made his living via various means. Originally destined to be a priest in the Church he had to flee Rome for unknown reasons, and was never accepted back into the church by the Pope, despite his appeals. He has been described as a as a teacher of Physics, French and Italian. He claimed that one child by his first wife, had been kidnapped in Paris, his wife died shortly after (~1776), and Gasparo went travelling. He was also described as a Professor of Mathematics, and displayed models of Rome and Paris, and later displayed a model of London in London, 1785. He married his second wife (aged 21) in 1781, when he was 52, and died at Bath 27 July 1801, aged 71. His obituary in the local paper described him as "a linguist and father of the promising young actress of that name at our theatre".

Born in Paris in 1784 and named after Lady Suffolk, by whom she was partly brought up, and of whose daughter, Lady Catherine, she became a close friend. She became an actress, starting at the Theatre Royal in Bath (1800 - 1803).

Julia was famed for her youthful beauty and talent and had made her London stage début in 1804 as Juliet, after making her first appearance in Bath (1800 - 1803), then Haymarket, London (1804). In October of 1804, she contracted to play at the Theatre Royal, Liverpool, as Juliet to Her future husband's Romeo. On 9 March 1805, she and Charles Mayne Young married at St. Ann's Church, Liverpool. They contracted for a twelve-month on the stage at The Theatre Royal, Spring Gardens Manchester.

This theatre was a plain brick building (replacing the original that burnt down in 1789), standing 102ft long by 48ft wide: a small theatre with pit, gallery and boxes. The side boxes ran parallel to the exterior walls, with front boxes curving round in an ellipse. The proscenium (stage in front of the curtain) consisted of ‘six Corinthian pillars’. The Theatre was demolished in 1869, to make way for the Royal Exchange, and the spring, from which the square is named was found 15ft under the stage. In the late Middle Ages water from a spring was brought along elm pipes to a conduit in Manchester where the townspeople could fetch water. The spring gave its name to both Spring Gardens and Fountain Street.

While on the stage in Manchester, Julia visited St Mary's, during her visit she had a premonition of her death and asked to be buried on the spot where she was admiring the view. Before the year was out she had indeed died. After giving birth to her son, Julian Charles Young, she fell victim to puerperal fever, dying 10 days later, on 17 July 1806 at the age of just 21.
