It appears that the first member of the Harache family to make the journey to London as a result of persecution, was Nicolas. He came with his wife, Marie Mascrier, and their daughter Marie, sometime between August 1667 and November 1668. Their son, Thomas, was born in London in 1668 and his name appears in the baptismal list for Threadneedle Street church dated 29 November. So far, no records have been discovered, either in Rouen or in London, that prove Nicolas was a master goldsmith. There is no record of his work or where he and his family lived, although the church where his son was baptized indicates that he had taken up residence in the general area that was later occupied by the members of the family who followed him to England.
