Maybe coincidence but my grandfather's grandfather was Firth Thackrah bap 20 April 1828 at Hartshead, Yorkshire (between Brighouse & Dewsbury). He died 25 Jan 1896 at Ilkley. Firth's parents were George Thackrah (a butcher) and second wife Mary Firth (married 5 Feb 1823 at Tong). Her parents were Robert Firth (a farmer of Tong) and wife Elizabeth. Firth Thackrah later known as Thackray. For further details of my Thackrahs see my follow-up to Mike Smith's enquiry re James H.Thackrah and more to come.
