Hughes in Edinburgh

[Woodster]

Hi

I am trying to trace the Hughes side of my family and have John Hughes and Ellen Kane  (my 2 g's grandparents marrying) in Lauriston Street Chapel In Edinburgh in 1870 - Their parents on the marriage entry are Richard Hughes - Crofter / Ellen Hughes nee Walsh  and  Patrick Kane (Kain) / Mary Kain nee Murray.  I am suspect that the parents of John and Ellen lived in Ireland in 1870, as I have tried to find them around the Edinburgh area. 

I wonder if anyone might check if the parents lived in the Midlothian area please.

Any help greatly appreciated.

Thanks

Woodster
