Chesney, Cheney, Etc. LNAB

Question

I have been merrily merging the Chesney and de Chesney families.  Now I have come to a decision point: When to switch to Cheney.  FMG only uses Chesney.  There are no WT profiles for Chesney between 1200 and 1700.  I propose:

1. Merge pre-1200 profiles into Chesney

2. Merge 1200-1700 profiles into Cheney and de Cheney profiles into Cheney, unless another name was actually used.

3, For profiles after 1700, merge within the name they already have (unless it is wrong.)  This would include Cheyne, Chaney, Chesney, and Cheney, at least.
