No. When you view the full profile, you will see a Curator Note for each reinforcing that they have different parents and married different women -- even though born the same year, albeit in different places. To confuse things further, both wives are named Elizabeth.
I have my doubts about the death date and location being the same for both, though. I haven't yet noticed anything reliable enough to confirm or deny that death information for either profile (not that I've been looking very persistently).
If one comes across another George Washington Gunter profile without parents to help identify which profile to which it might be a duplicate, then hopefully there will be profile birth location details and/or spouse, siblings, and/or children to help decide where to merge it (or not!).
There are enough unknowns about the correctness of the siblings & children that I've not been ready to lock the relationships yet -- in hopes that someone will have information which will help "sort out" the siblings & children of these two G. W. Gunters.
