William Ellis (1824-1883) is my gt, gt grandfather. He married Mary Ann Harrington 24 July 1841 at Aston Union Register office. The witnesses were Jane Hawksford and George Thomas. William was a glassmaker of Birmingham and Stourbridge from at least 1841 to 1886.
Mary Anne Harrington (1824-1899) is the daughter of John Harrington (1781-1860) and Susanna. Mary Ann was born 4 Nov 1824 and baptised at St Philip's Birmingham 24 Dec 1832.
To answer your question, John Harrington was a glassmaker. His constantly changing abode reflects the tenuous employment situation of a Victorian glassmaker. Heneage Street, Aston, Dartmouth Street, Birmingham, Dudley, Oldswinford and later Wollaston. All of these areas had glassworks in the Victorian era. He was born at Winchcombe in Gloucestershire. The census enumerators sometime write this as Witcham (which is how it is pronounced). I doubt that John ever formally married his life-long partner Susanna. When they baptised their three youngest children at St Phillips, Birmingham on 24 Dec 1832 the officiant marked the parish register as "single woman" with an exclamation mark. Which, sadly means we may never know her maiden name.
