I see that in the 1901 census John and Rebecca have an adopted daughter, Kate Eberth, born in Middlesex, like Rebecca.Somewhat intrigued, I found the birth of Kathleen Eberth in 1892 in St Pancras registratio district. i did think she might be a child of Rebecca's, but can't find any record of a Rebecca Eberth. So perhaps this Kate was a niece. Anyway, nothing to do with our immediate line of research
I haven't got much further with the Lees. One census entry says John Lee was born at Allenheads, and there do seem to be a lot of Lees up there, including one who is a miller, but I haven't seen an obvious birth fro him. And as for the Todds....!
