When I was in school, there were 2 boys, brothers, whose names were Zachariah and Zebulon. They got made fun of a lot, even though they were called Zac and Zeb. Another girl in my class was called Tisha. People called her Tissue. Another boy was named Galen. People called him Gayfag. I remember one boy who had a normal name, Patrick, but people called him Patricia.
The name of a child will not determine if they will leave a legacy of truth or not. A child named Pig could grow up to be the President of the United States, while a child named George Abraham Jefferson Truman could end up being a pig farmer.
Yes, I think they will get made fun of, and will strongly desire nicknames. Or Zephaniah may want to keep his first name a secret and be called Joel or Isaac, and Ana may want to just be called Ana or Ysobel or Julia.
You may like the names, but think of how your kids will feel when they get made fun of. Its easy to hide a middle name, but sooner or later everyone will find out (graduation, teacher mistake), and they will feel humiliated like its the end of the world'. I've seen it happen.
I was also checking a girls drivers license once to verify her age, and her middle name was Princesslayah. She was pretty embarrassed about it, although I didn't say anything. Parents have good intentions, but good intentions aren't a good excuse for cruelty.
