ID of calligraphy font please

I'm trying to determine the font of Aubrey A Gray in this sample. I've run it through multiple font searches with no luck. I can't seem to replicate the A, G and b in the same font. Any ideas? It doesn't look that tricky, but thus far, I haven't been able to find a match. The letters look too consistent to be hand lettered. Thanks in advance for any help!
