dawnsh, you star!
For information - this thread started as a search for a marriage between Basil SANDYS and Caroline GREENHILL which (although banns were read in Lambeth) never took place.
It has developed into a search for marriages of Basil SANDYS:
1) to Catherine DEVANEY (eldest daughter born c1826)
2) to Catherine GERAGHTY ?21 Sep 1837. (daughter born c1840).
If there were marriages they were most likely in Roscommon as there were local DEVANEY and GERAGHTY families. The date 21 Sep 1837 for marriage (2) has no primary source attached.
