Hello there,

I see on the I.G.I.'s (FamilySearch.org) that your Elizabeth shows as Chr. 15 Feb 1827 at Saint Mary's, Castletown - parents noted as Richard & Elizabeth CORRIN. You could scan through after 1827 for any siblings.

Her marriage is also there, 03 Oct 1852 at Braddan to Wm. CALDERWOOD.

My Corrins are also from the Castletown area, but this Elizabeth does not appear in our line.

Good Luck,
Marjery
