As much as I loathe Ancestry.com for acting like a big genealogy-hoarding spoiled brat (she said kindly), I appreciate the state of Kentucky for being so generous with their records. If you have a subscription to Ancestry.com and lots of folks in Kentucky, like I do, you're in luck, ma'am. Or sir.
I've been trying to restrict my research to looking up grandparents, aunts, uncles and first cousins, who tend to be neglected in the wake of finding new family members, and "firming up" their information - finding death dates and places, forgotten children in censuses, etc. Kentucky's vital records have been most helpful on my Smith, Mobley, and other Kentucky families.
The actual death certificate images are available from 1852-1952 and most of the years between; there are a few years missing. I've made a few sad discoveries - an uncle died at the state asylum, a cousin died of pneumonia after her tooth was extracted (no antibiotics yet), and another cousin died of cancer of the tongue, yikes! - but the death certificates have also been very valuable in terms of getting more complete and accurate information on some family members, and discovering new people in the process.
When the Church is finished digitizing its millions of microfilms and makes them available FREE online in a few years, I'll be the first in line to see them... in the meantime, Ancestry.com is a somewhat necessary evil.
