The only Arthur Gartside born c. 1817 in my database, is Arthur, son of Enoch Gartside and Alice Wood baptized at Dobcross Holy Trinity 1 Dec 1816.
Arthur married Mary Brierley in 1837 at St. Chads, Saddleworth and they had 11 children that I know of:
Alfred - 1838 - married Eliza Wood at Friarmere
Alice - 1840 - married a John Wirgley 1861 at Friarmere

Jane - 1854
Benjamin - 1856
Sarah - 1857 - married John E. Langfield at St. Chads

This family can be traced back to Ralph Gartside who died in 1658.
