Lilias Walls and Robert Armstrong

[thomson10]

Hi,
I am looking for information on my 4th Great Grandparents Lilias Walls and Robert Armstrong.

I am looking for Lilias Walls mother, i have her father listed as James Walls, but their was no mother listed on the birth record. Lilias was born June 04, 1788 in Torthorwald, Dumfriesshire, Scotland.

I am also looking for both parents of Robert Armstrong. I believe he was born about either 1788, not sure where. I have Lilias and Robert's marriage record, but it does not show any parents listed for either. They were married Jan.26, 1808 in Langholm, Dumfriesshire, Scotland.

The only census records that I have found, that might possibly be them, are 1851 to 1871, they show a Lillis and Robert Armstrong in Cumberland, England

Any help would be greatly appreciated!
Thanks,
Murray Thomson
