You have the right father (which I already have this death certificate), but not the right mother. In George William Hammond's death certificate it has the mother as "don't know." And in the first census he's in, it clearly states that George was born in Arkansas, and that his father was also born in Arkansas, but mother born in Germany. But at the same time it shows James Andrew's (sometimes he was referred to as just Andrew) wife was born in Arkansas...
What I do know is that my Grandad mentioned that his mother (George William's oldest daughter) could speak Dutch (either it's German or Dutch for there are some comments that they came from the low countries, with Luxembourg being the one mentioned the most.
