Thank you. I think I know the building you mean.
Yes, my direct ancestors, Thomas and Mary Parslow ( 3 x Gt Grandparents) and all his children including my 2 x Gt GF, William Parslow, were in fact members of the Heathen Street Independent Chapel which I am led to believe was on the site of the United Reform Church and is different from Brick Lane Baptist Church. I was in touch with the archivist of the UR Church and he confirmed that the Heathen Street I.C. was originally on that site. Apparently one branch of the family continued to worship there after it became the Congregational Church and then the URC and one, Albert Jack Parslow, who was killed in WW1 is named on a memorial inside the church.
A lot of the buildings I would like to have photographed have been demolished over the years and new roads driven through. Also, the census returns often don't say which house number each family lived at.
I will certainly get back to you if I cannot locate any other streets.
Thank you.
