Re: Robert Charnley death IOM late 1800 early 1900

I don't think would be relations from Newcastle. When Robert remarried basically disowned his son Laurence. If this is Margaret when son William & Emma is a 12 years gap in ages. William born 1861 and Emma 1873 so if Emma was 4 in this picture William would be 16 but looks more like 10-12? Unless more children I don't know about?
