According to babynameshub.com,
Shiloh is more popular as a feminine name, as there is a total of 2,684 girls that have been named
Shiloh since 1880, while there is no record of any boys that have been named
Shiloh since 1880.
Personally, I prefer
Shiloh as a masculine name, due to only seeing the name as the name of a male character in a book series I read. I have also met a male dog named
Shiloh. I also think
Shiloh sounds like more of a masculine name. (No offense to any girls named
Shiloh!)
