Thank you for those details Joan (assuming you may get to read this 9 years later!)
If anyone on this thread is still interested in Sarah B DARRELL nee RICHARDSON's ancestry, check out my blog filtered for Bermudahttp://lornahen.blogspot.co.nz/search/label/Bermuda
and for Sarah's father's page on my webpageshttp://familytree.lornahen.com/p56061.htm
My interest is in exploring a connection to my RICHARDSONs of Morebattle, where Sarah's father James came from.
Also interested in who the other surviving daughter of James and Mary (MOFFATT) RICHARDSON was, as when Mary died, she was listed as being survived by 3 daughters and 9 grandchildren.
Catherine H Moffatt FRITH nee RICHARDSON had died.
Martha Aitchison KEENEY nee RICHARDSON was probably still alive (in Alabama in 1870).
Sarah DARRELL nee RICHARDSON was still alive.
Susannah Cox RICHARDSON died young, as did a sister Mary.
There are sufficient birth gaps for a third surviving daughter to fit.
