Hi Kate,
That's great! Though unfortunate that her mother's maiden surname isn't there - I take it that's the case?
The only possible relevant IGI entries I could find are:
An Alexander P marrying a Mary anywhere in Scotland, 1800 +/- 20; there was just one entryAlexander PITTENDRIGH m Mary LOVIE, 26 Jun 1814, Pitsligo (that's a bit late if Ann's age is correct on her death cert)
An Alexander P and a Mary having children anywhere in Scotland, same time period; again there was just one entry Alexander PITTENDRIGH and Mary MILNE had a daughter Margaret bap 1808, St Nicholas, Aberdeen.
Perhaps there might be more on SP?
I am wondering whether there might be directories for the time which would include, Alexander PITTENDRIGH, Undertaker.
There's a gravestone which looks interesting (the combination of names!) on the ANESFHS site at:

You might like to post a request for a lookup of the full inscription in the relevant MI booklet?
