Noo Oma told me it was My grandmothers uncle was Kiefer, but she hasn't lived in Germany for a good 60 years. But you, m'dear, would know .
Mmmhh... you know it could just be an old fashioned name that's not around much anymore...After all, you Oma's Uncle would have been named roughly 100 years ago... So it's all possible! I learn something new everyday! Hehe
I do love the name, though
