That the Emptages of the Isle of Sheppey were genetically linked to at least one branch of the Emptages of the Isle of Thanet has been proved by DNA tests.
Whilst the chances of finding a documented paper trail confirming the link are highly unlikely, the study of the baptism and marriage parish registers, coupled with the use or re-use of certain names, has identified the Emptages who probably migrated from Thanet to Sheppey, the place that they stopped at along the way and when the migration happened.
