Hi Shirlea. I agree with you that they appear to be the same person. The reason the name displays as it does in the profile you linked to is that the profile manager entered Merritt, rather than her married name, as the Current Last name. I think that is allowed because a female may choose to keep her maiden name, and go by that, rather than adopt her husband's surname. (I don't know if that convention existed in the 1700s however). My guess would be that, in this case, the profile manager of Merritt-2123 just made an error in entering Current Last Name. Normally it does make some sense to display both a LNAB and a married surname, since a researcher might find relevant records cataloged under either name.
