Have you checked the Mormons website to see if there is an event
listed for your CHRISTINA HARVEY LAW?
If you are unlucky it is still worth your while to check the Indexes to
the OPRs at your nearest Mormon FHC [Family History Centre].
Have you checked for death certificates for the parents? You can check
the indexes at your FHC or from the Origins Website, costs £6 for 30
This site is the indexes only, if you find a hit you need to order the
certificate from them or cheaper to buy at your FHC.
When you have a firm location it is often worthwhile to see if there are
any published MIs [Monumental Inscriptions]
