Mike, this is my family. However, I am not sure where LDS got the birth date from. I already have a record confirmation from the National Archives (Record BXCB 221771, Page 243, Vol.1 Dec 1842. Dist: St Pancras; County Middlesex). The LDS date may be her confirmation date.
What I am trying to confirm is if this Henry Brooks is the same Henry Brooks listed as Cox Brooks' son in his will.
Thanks, Bob
