The following year, on 7 December 1791, Asgill was once more involved in a court case, this time at the Old Bailey. His servant, Sarah Paris, had stolen some items from him. She had passed some of these items on to William Turnbull, a servant of Colonel Banastre Tarleton, who had fought in the American Revolution with Asgill. Asgill stated that she was pregnant and has another child with the supposed father absent. Turnbull was likely the father of the unborn child and stated in court that he was not her husband, but that he had cohabited with her.
