Hackney embroidery/silks shop

I wonder if anyone can help me or point me in the right direction. I’ve been doing some research on my family tree and a family member Hannah Mariah Smith shows up in the 1901 census as living in Elderfield Road and the family have said she had her own embroidery shop in London (I presume it was in Hackney as that is where she lived). Does anyone have any pictures or name of the shop or is there anyway I can do some research into this?
