YES. But that's not just a recent obsession, I've basically always loved thrice as many A names as I've loved other names.
and that's just off the top of my head.
I too have always loved "A" names, but mostly for girls
Ava, Autumn, Ariana, Alyssa, Anna/Annabel/Annie, Amelie, Alessandra, Alice, Alaska, etc.
For girl's I've also always loved "M" and have recently fallen in love with/am currently obsessed with "L" and "S" names
Mallory, Melody, Maura, Maeve, Madeline, Molly, Mckinley, Madison, Mirabel, etc.
Leah, Laura/Lauren/Laurel, Luna, Lydia/Lynia, Lavinia, Logan, etc.
Stella, Sadie, Summer, Soleil, Spencer, Shannon, Sailor, Sage,
Boy's names are much more spread out, the only letter with a true abundance of favorites is "S"
Scott, Simon, Spencer, Seamus, Sean, Samuel, Sebastian, Salem, Sonny, etc.
