Not been able to find any records online for my 3rd great grandfather James and his wife Margaret other than the marriage record. If anyone has any information or records on these family members, I would love to hear from you. My mum and myself are both on GEDmatch RX9251551 DK2509312 FM7417171 

Any help would be greatly appreciated as tracking my mum's family has been difficult, as my gran was adopted out into the workhouses as a child in Scotland so had no family information or records.

Thanks

Linda.
