A few years back one of my maternal relatives worked out a family tree. Today I found it on webarchive and since then have been able to confirm back 8 generations through OpenArchieven. There are records of my ancestors at each stage. This is amazing.
The reason I have not been able to do so before is neither my Oma nor Opa are in the records as scanned so far. So this personal family history book can now be really recorded with links and I’m just so excited. I am not sure if I can find any further back, but this is a super important part of my history I never knew, never had any real ability to find out before.
