It is unclear which lineage Edward Bletz falls under.
However, there are a few things of note.
1900 US Census reveals Father was from Pennsylvania, cryptically, and Mother was from Germany.
We might assume then Edward's mother is connected somehow to the Kramer family.
Whether from August Kramer's father's lineage, or his mothers, remains to be seen.
The age shouldn't be a problem either for a real 2nd cousin, as 2nd cousin denotes August's grandaunt's grandchild.
Finding out which one will require a lot of legwork in Germany, at this point.
