There is a lot of discussion out there on the correct LNAB of this woman. I can find just as many sources that call her DeRuel as Duvall. However, we need to pick one name and do the final merge in this family.
The other active profile manager can provide her input, here is mine. I believe her LNAB should be DeRuel, as it is the recognized maiden name of Edward Moberly's wife in the DAR and SAR databases. I believe the confusion with Duvall was caused by well meaning biographers trying to find a family for Elizabeth and there were two Elizabeth Duvalls born in Maryland in that time period. One who died without marriage, albeit, this has not been confirmed and one who married William Fowler. My other inclination towards the last name of DeRuel is that a grandchild was given DeRuel as a middle name.
Any input from anyone will help us with this decision.
