Hiya Lad, thanks for the reply.
My connection here is that Mary Hoare in the 1841 census is the widow of William who probably had a sister who was probably my grx3 grandmother.
Mary's son William is identified as "miller" in 1841. Quite possibly he worked for the Rickards, then, if there was likely only one mill there. Could be that the mill had belonged to Mary's husband William Hoare (since he was a miller when he married Mary Libbey in 1816) and the Rickards took over when William died.
This is probably the baptism of young William Hoare in 1822 in St Enoder (15+ in 1841):

Aha, looks like my surmising is correct:
http://www.cornwall-opc-database.org/search-database/more-info/?t=burials&id=2150654Father William Hoare was buried in St Columb Minor in 1838, aged 51, residence "Kesstell Mill itp".
For the Rickard connection with Kestle Mill ...
Enoder Rickard aged 72 was buried in St Columb Minor in 1849, residence Kestle Mill:
http://www.cornwall-opc-database.org/search-database/more-info/?t=burials&id=2150931The only other burial I see showing Kestle Mill as residence is for Mary Rickard aged 78 in 1854.
The first Rickard baptism there seems to be Catherine in 1853 (born 1849, parents Enoder Rickard and Elizabeth Lawry).
So it does look like William Hoare and wife Mary were at Kestle Mill prior to 1841, and the Rickards took over after William's death, with young William continuing on working there for a while - in fact, the two households are both at Kestle Mill in 1841, so one might still think there was a connection! It looks so much like there might have been a Rickard-Hoare marriage, but I don't find one. Maybe just a Rickard-Hoare birth.
The next series of households is at Quintrell Down(s) where there were numerous Rickard BMDs in the 1st half of the 1800s.
Young William Hoare and wife are still at Kestle Mill in 1851, with him a farmer, while Enoder Rickard at the same location is miller. There are two other households at Kestle Mill, miner and ag lab, so it seems to have become an "address" rather than referring to just the mill itself. (Present-day Google maps seems to give Kestle Mill as a location - wikipedia says it's a hamlet - with Kestle Farm located there.)
We can contact each other through the private messaging system at the site here. If you're related to the Rickards and can see a connection with the Hoares other than the proximity and apparent transfer of the mill from Hoares to Rickards, I'd be happy to direct you to more info about the Hoares. William, the first child, seems to be left out of most family trees likely because the surname was spelled Hore on the baptism, and my presumed grx3 grmother just doesn't appear anywhere, but in any event my own connection with the Rickards would likely be distant even if there was a Rickard-Hoare marriage or such.
