Georgie sounds like a good name, and it can be either male (George)or female (Georgina).
Im trying to keep our initials the same because both my boyfriend and i have the first 2 initials RA. For a girl i like Rosa Aleshia, and for a boy I like Rafael Angelo.
Another suggestion is to pinch family names. My older siblings have the same middle initial, but my younger brother and sister have the middle name of a relative who passed away while my mum was expecting.
