Middle name help for Fergus please

We're having our 3rd and are struggling for a middle name and don't want to leave the third child without 🙈. First child had my first name choice that husband hated -now loves as his middle name; second child after my Granddad who passed away whilst pregnant and struggling for third, we want to avoid family and the stress of leaving someone out as. We've both got step parents and step grandparents etc. Surname begins with H so avoiding names beginning with H as it's a mouthful. Thank you ✨
