Hello all,
While I was having a grand old time going off on a fascinating tangent with the Revd Robert Aitken, his two wives, and his children who were born in three places simultaneously, Jack was gathering data behind the scenes. He proceeded to send it to me so he could go out and get the newspaper and do the crossword

So I will do my best.
First of all he found these two young women with farmer Andrew Young & family:
--
Jack wrote:1851 census. Linlithgow, West Lothian.
White Cunlks Farm. ........ [possibly Whitebaulks? Farm]
Rubacca ARTHUR, 23, House servant, b Cumerusde, STI
Agness ARTHUR, 15, House servant, b Cumerusde, STI
--
Perhaps the above birthplaces are Cumbernauld? But that is in DNB....
The 1851 WLN census CD has Rubacca & Agness as AITKEN.
But their birthplaces in STI were as illegible.
So the original census page might be rather poor for reading?
This Agness is a tad on the young side...?
Agnes is a bit young, as Jack suggested, but we have seen worse!
Then he compiled all the IGI information on the family, some extracts [EXT] and some submissions [LDS Sub]:

So... I will leave you all to chew on that, while I get back to the Reverend in Pendeen, Cornwall. It is really fascinating

I may report when I'm done, although this family belongs to the "posh" branch of the Aitkens

Still, if that was Robina in Liverpool in 1851, there may be a connection.
All the best,
Sarah
