You may already know this, but maybe this will help others to help you:
Name: Daisy M Rios
Birth Date: 14 Oct 1945
Address: 2635 Fuller Rd, Burt, NY, 14028-9791 (1995)
[61 Slate Creek Dr Apt 5, Buffalo, NY, 14227-2805 (1992)]
[260 Rhode Island St, Buffalo, NY, 14213-2229]
[868 Main St, Buffalo, NY, 14202-1403]
I did a reverse address search of her most recent address (Fuller Road). The Zillow entry says:
2635 Fuller Rd, Burt, NY is a single family home that contains 1,200 sq ft and was built in 1993. It contains 2 bedrooms and 1.5 bathrooms.
Using that address, I searched the Niagara County Assessor's records. Daisy did in fact own this home. In fact, the owner's are still listed as Daisy Rios and Robert Berwick and the most recent sale was for $1 (in 2015) which typically suggests the sale was for a change in the deed or the property was gifted.
A reverse address search on the whitepages shows that there is a R. Berwick Sr. (in his 70s) and an R. Berwick Jr (in his 40s) at she same address as above. Maybe try to contact them to ask about Daisy's current whereabouts.
Hope this helps you!
