A Shenoa Diamond
Shenoa is a bit hard to dig up info on regarding the meaning and origin. Variants include Shenoah and Chenoa, and multiple pronunciations including SHEN-oh-ah, CHAY-no-uh and CHEE-no-ah, so take your pick, as no one is going to fight you on the right version. Most baby name websites have it listed as a Native American name meaning "dove," from the word chenowa, "dove of peace" or "white dove," which is inaccurate according to various Native Americans, but is backed up by the state of Illinois in this bio, where there is a city called Chenoa, supposedly pronounced CHEE-no-uh. The more likely possibility is that it was once a Native American place name, and Wikipedia claims it is based on one of the Native American words for the Kentucky River here. Some sites even claim it means "a radiating presence of love," which has nothing backing it up. Considering the listed meanings, there is only evidence to support it as a unisex name. A possibility for nicknames is Shea or Noah for boys, Shay or Noa for girls, although Shen is an option as well.
The name is usually as common in Australia as it is in America. There is a jeweler called Shenoa Diamonds, a famous Spanish pop singer named Chenoa, and a rock band called Shenoah. There were no babies named Shenoa in 2011, but there were 23 baby girls spelled Chenoa. I believe this name would be a great way to honor realtives or ancestors in the Kentucky area or those with a Native American background. It would be a good idea to get the insights of your relatives, and they might have something to contribute to the meaning of this name that I couldn't find online. If anyone has any new information, I'd love to hear it.
