Catherine, Grace and Lucy Scantlebury CRABB
I am also looking for info on Lucy Scantlebury Crabb, daughter of Catherine Crabb. She was lodging with John Scantlebury in 1851 with Lucy and Eliza (see other message re Eliza!).
There's a marriage of Benjamin Crabb to Catherine Smith in 1843 in Bodmin, Cornwall. Ages are correct for it being the same Benjamin who was married to Caroline (although he is down as batchelor!).
In this marriage Benjamin's father was James Crabb, an Inn Keeper. Benjamin was a woolcomber (as was his stated profession in 1841 wiuth Caroline and Eliza).
A Grace Crabb was witness ... could be mother or sister of Benjamin.
Any help would be great - please check your CRABB trees for Benjamin c1816, Lucy 1850, Eliza 1840, and also James, Grace and Catherine Crabb.
