My Great Grandfather was William George Eckersley, whose details appeared in the 1901 census, showing him as being born in Manchester in 1880 and in 1901 was newly married to Emma Brumby Dent and living at 117 York Street, South Manchester and he was described as an Employer Fruit Salesman.
His father and mother William Eckersley (age 45)and Annie Eckersley (age 46) along with their three younger children also appear in the 1901 census living at 75 Alexandra Road Moss Side Manchester.They are all shown as having been born in Manchester.This William is described as a Fruit and Potato Dealer, working from home.
I have searched the 1881 census on the websitewww.familysearch.org/ and cannot find any trace of the three of them.This strikes me as odd as I have identified virtually all other relatives in that census.
I have a vague recollection that sometime in the past an old great uncle (the eldest son of William George and Emma)had mentioned that the surname Eckersley had been taken to replace Gregory.This is supposed to have occured because there were two Gregory Families working at Smithfield Market in Manchester and they wanted to avoid confusion.
I can't find them in 1881 with the name Gregory either!
I don't know if you have come across this at all in your researches, William George and Emma had six children so that now there are quite a few Eckersleys on this line now around.
