Not sure what the relevance of that is, but Jane Calvert Walker, aged 0, mmn Calvert, died in Dundee in 1861. Another Jane Calvert Walker, mmn Calvert, was born in 1864, and died in 1866 in Tradeston. A third Jane Calvert Walker, mmn Calvert, was born in Tradeston in 1866. Tradeston is in Glasgow. Parents of all three were Joseph Walker and Jean Calvert.

Sarah Walker b 1855 in Sunderland was the daughter of John Walker and Mary Ann Calvert.

Thank you again for your replies, so helpful.   I have found a James Walker on the 1881 census in Sandiacre Derbyshire aged 20, a moulder born Scotland. I am puzzled to why he gave different locations in Scotland.  I am going to continue researching with the hints you have given me.
