Historical cause of death 1600s-1800s
What did overlaid mean on a death certificate?
On a death record, overlaid meant an infant found dead in bed with its parents, judged smothered in their sleep. In modern terms it usually pointed to accidental suffocation or what would now be examined as SIDS. Whole families shared beds, and modern readers should resist judging; many such deaths would now be called cot death. Expect it on records mostly 1600s-1800s.
Also written on records as: overlaying, suffocated in bed, smothered.

FAQs
What is overlaid called today?+
Accidental suffocation or what would now be examined as SIDS, broadly speaking. Doctors of the period diagnosed without laboratory tests, so one label often covered several conditions we would now separate. This page explains historical record language and is not medical advice.
How was overlaid written on death records?+
Clerks and doctors also wrote overlaying, suffocated in bed, and smothered. Spelling wandered from register to register, so check every variant before you decide a record is missing or wrong.
Where do these definitions come from?+
