Actually, Mark - because it's you - I double-checked, and it turns out I posted the wrong details. The silk-weavers' son was James Flemming. You were quite right to nag! So, to put the record straight...
The Joseph Flemming (of lowly parentage) I should have told you about was born in Bethnal Green to George (shoemaker) Flemming and his wife Sarah. He had two (much) older brothers, George and Charles, who were a shoemaker and a wood-chopper respectively. The family may first be found together in the 1861 Census, as follows:
I can't quite make out the street name - it looks like "Tumble Street", but it's unclear. Suffice to say it's Bethnal Green, and this Joe was born there circa 1858/1859. It is he, I believe, who is likely to have ended up as the French polisher workhouse inmate at Poplar in 1881.
