My grandfather's name was Frederick John Bigg, born 1871 in Lambeth, London.
He had 9 siblings - none of them was named William.
My great rg.father's name was Thomas Frederick Bigg, born in 1833 in Poplar. Many of the Bigg family were grocers or butchers.
Family names are Jakeman, Page, Cobbold, Owers.
Like you I have been looking for an ancester for a long time. I am looking for John Bigg - born probably between 1780-1800.
I hope you are sucessful finding yours!
