Uh, you're 0 for 3. Not singling you out, because many others in this thread have made the same mistake — but either you don't know these songs, or you've failed to read the thread title.
Lori McKenna - Susanna Singer-songwriter from Stoughton/Massachusetts. "Susanna" was inspired by Guy Clark's wife Susanna Clark, who died from cancer in 2012. A track from Lori McKenna's album "Massachusetts" which was self-released in 2013. "Susanna, what's he gonna do without you When you know he's not meant for this world alone Susanna, who's he gonna sing to now that you're gone"
Eels - Agatha Chang From the album "The Cautionary Tales of Mark Oliver Everett", released in 2014 on E Works Records. "Agatha was beautiful Her long black hair and aching eyes"
Daisy Bell (Bicycle Built For Two) ~ misc Betty and Dupree ~ Chuck Willis, Grateful Dead Charva ~ Frank Zappa Josie and the Pussycats theme
Gillian Welch - The Way It Goes From her album "The Harrow & the Harvest", released in 2011 on Acony Records. "Becky Johnson bought the farm Put a needle in her arm That's the way that it goes That's the way"
SHFers gonna SHF, I guess. First song I thought of was by Concrete Blonde, which fits the OP's criteria completely. (Name=first word of song AND complete title of song.) Only problem is I'm pretty sure "Joey" is a guy, not a girl, although the gender is never specified. (In real life Johnette wrote it about her relationship with Marc Moreland of Wall Of Voodoo.) So if you're open-minded, this one works.
