Hi Jason, back now. Brother in law's 50th Birthday party in a big country hotel....crazy

Hopefully you can access the LDS/Family Search census details for Alexander, Catherine and family elsewhere.
I love American obits! They are the full blown genealogy bible. The UK stuff is insignigicant compared to the US for this.
I did see a couple of Catherine Dearies births in the Glasgow area on Scotlands People yesterday but showing as 1886 not 1885. Corresponding census entries too I thought for 1891/1901. Hard to say more for now... I would guess for now that Dearie/y is Catherine's maiden name in terms of common practice and how maiden names were used for Scottish women (regardless this was in the US). But, needs to be confirmed really.
Would Catherine Deary Shields's death at the age of 99 (not confirmed, but likely the right entry from what we have) have merited an OBIT...very likely. We had from earlier:
Catherine Deary Shields d. 3 Jan 1985 at Dade, Florida. Age 99 (nearly got to the century!). White and birth date: 13 June 1885.
Not sure or confident as always about US sources, Jason. Perhaps you can have a look around there for a possible obit for Catherine Snr?
Monica

PS: Guess your family line has not had anything to do with the descendants for Alexander & Catherine Shields in Miami over the years?
