Need a beautiful girls name and strong boys name?

Guy-means warrior. You can try to make up a name like Garison. I'm sorry I don't know many boy names that start with a"G". Other cute boy names are Colton, Cole, Dreighton, Ryall, Shade, Xander, Xavier. As for girl names, which seem to be easier to find or make, I thought Amberlynn, Annaliese, Rhiann, Brianna, Alyssa, Jaselyne, Kendall, Rayne. Hope it helped
