Hi there!
So FH and I both have German heritage. FH has definitely honored and embraced his more so than me (for no other reason then ignorance/lazy on my part) as he speaks fluently, and incorporates German aspects of life into our daily lives. Which I completely support and its encouraged me to embrace it a bit more as well. We are even incorporating some time in Germany into our honeymoon! Anyway, ... we researched German wedding traditions and came across this one:
Baumstamm Sägen

for the ceremony and are 100% excited about having this. I can honestly say I have never attended a wedding where this occurred, and I think it is such a nice gesture.
