Yes, ok, I see now:
1851 William and Eliza Earl living in Newmarket, Horsley
1855 Wm Earl dies - address: Newmarket, Horsley
1861 Eliza Earl, 35, widow, cloth worker, living on her own in Forest Green, Nailsworth - born in Downend (v.close to Horsley)
1871 Eliza Earl, widow, cloth worker, born Horsley, living on Chestnut Hill, Horsley with son George (7, born Avening) - George must be illegitimate since William Earl died in 1855
1881 Eliza Earl, widow, cloth worker, born Horsley, living in Upper Forest Green, Nailsworth, with sone George William Earl (17)
1891 Eliza Earl, widow, retired cloth spinner, from Nailsworth, living in Upper Forest Green
I can't find a death for Eliza, or a GRO birth or baptism for her son George. There's a possible baptism for her husband, William Earl, at Forest Green Chapel in Nailsworth. This was the local congregational church and the other Chandler family I've been looking at (Enoch, son James Sansum Chandler, et al.) were connected to this Chapel. The chapel records are very patchy, but I'm wondering if this accounts for the lack of BMD records and maybe starts to bring together the family of William Chandler (of Windsor, NSW, d.1873) and his brothers John and Christopher, with the Enoch Chandler family - they all seem to have been in the same place at the same time
