baby girl name undecided! ..Spelling???

I’m really REALLY stuck on baby names for either my baby boy or baby girl... This is my first one, miscarried last pregnancy and tossed all names I liked then... I’m Due last week of august. I would really like the name to be pronounced (eye • luh) but I’m stuck on spelling and I know it seems to be an older name. I’m thinking if baby girl is the case, baby Iyla/Isla and Mae or Margaret for the middle name. I’m absolutely stuck on baby boy names. The only one I’ve liked so far that’s ever stuck has been Liam. Please help haha, very open to suggestions for both, still waiting on my final gender/anatomy scan
