Interesting what was said about the two names for this street being used in 1841. I thought I had discovered when the name changed because on 1861 census my gg grandparents, Saul (Solomon) Solomons (born Davis) and Catherine (Kitty) nee Phillips were at 20 Petticoat Lane with daughter Rebecca. In 1862 when son Selig (later Alexander) was born they were at 20 Middlesex Street. Obviously this dual naming had gone on for a while. I was told the name changed because Victorian sensibilities were offended by a street named after ladies nether garments! Peter Solomon North Yorkshire
