Stepney Taggs

My GGGM was Eleanor Isabella Tagg. She was born on the 14th of May 1848 at 5, Voctory Road, Stepney the daughter of Henry Tagg and Emma (Nee Venables). She married Archibald Taylor on the 23rd of February 1868 in Mile End Old Town and had numerous children. Both Eleanor and Archibald are alive and well in the 1901 census. Her father, Henry Tagg married Emma Venables on the 1st of July 1839. He was a Paper Stainer as was his father, William Tagg. The IGI shows the baptism of a Henry Tagg on the 4th of July 1819 at Christchurch, Spitalfields, Stepney, the son of William Tagg and Maria. There are numerous baptisms and marriages of Taggs in Spitalfields,with William and Maria having at least eight children. The IGI also shows the marriage of a William Tagg to a Maria Bradley on the 14th of July 1799 at St Botolphs, Bishopsgate. Does anyone have any more information about this family of Taggs?
