Hi Linda,
I think my 4X great grandmother Mary Laughton nee Robertson is possibly the sister of Susan's father, Joseph.
So far I've been unable to find concrete evidence to link Joseph and my Mary but I think you'll agree that the following evidence of their closeness indicates that they were almost certainly related in some way.
My Mary Robertson married Samuel Laughton, a sailor in Peterhead in 1824 and over the following years both Samuel Laughton and Joseph Robertson witnessed the baptisms of each others children in Peterhead.
In 1841, both families were living in Milbourne place in North Shields.
Susan's brother Frederick was a witness at my 3X great grandmother's wedding and another brother James registered the death of Samuel Laughton in 1848.
Looking at the 1851 Census, Susan's mother Mary appears to have taken in the youngest Laughton child, Elizabeth when she was orphaned in 1849 following the death of her mother in the Cholera epidemic.
That's all for now but I'll get back to you with a bit more information today or tomorrow.
Kind regards
Carolyn
