Mothers are wonderful. Everybody should have one. 
My font Balava is based on Baskerville typeface, originally by John Baskerville. My mother was a Baskerville, and also suffered from Alzeihmer’s in her final years.
My handwriting, unfortunately, is not good enough to create a Calligraphy font, but I was able to make a usable font out of it with the help of FontCreator. The result was Hattha.
Calligraphic scripts take a lot more work to make into a quality font than most other fonts. Getting the spacing, kerning, and baseline alignment right is especially difficult.
