1861 & 1871 census lookup please

[CarolBurns]

Would some kind person on here do a census lookup for me please

I am looking for William Davidson, wife Elizabeth b Edinburgh and their sons. The eldest would be John Davidson Davidson (no typo error) b 1848 Edinburgh, William Davidson b Aug 1856 Edinburgh. They did have another son George Rankine Davidson b Nov 1861.

In 1856 they were living at 28 Dean Street in Edinburgh.

I am desperately trying to find this family as William b 1856 is my husband's Great Grandad. I thought I had all the details but they were wrong so am having to start at the beginning again for him.

Please, please help if you can

Thanks in adance

Carol
