Somehow my message got trunkated. What I meant is for part of my research one entry has listed a household member who is named Sily Treva

Neither FindMyPast or Anc has a transcription of Sily Treva for the 1911 census though...
FindMyPast has 317 transcriptions of Sily for a first name though; Only one for TREVA as the surname (and that's part of a hyphenated name).

Most Sily's are probably Lily's and in most cases it's probably down to the transcriber not understanding the letter forms as a capital L in a (not particularly) fancy hand can look like a narrow capital S.

Each household would have a census schedule left with them approx. a week before census night.
They were to fill in the details and then hand the schedule back to the enumerator who would collate the information into the books that we see for the 1841-1901 census returns.
This is why you can find more than one family within one household.
It is also why you can find people enumerated twice. They are listed on their home schedule because someone thought "well, we know exactly who will be here, let's get it filled in and finished with." then for some reason (often work related, but not always) someone ends up spending census night somewhere else and the head of that household correctly lists them as being present that night...

If the householder was unable to fill in the schedule they could have a neighbour, friend, or pretty much anyone else who was able to fill it in for them. It's only the people who couldn't fill it in or find anyone to help that would then be "helped" by the enumerator.

Thank you so much, Victor.
That pretty much completes the going forward I think.

Fingers crossed that one day I can find out Lucy's parents
And when Richard died/was buried.

I really appreciate the time and help you have given - thank you.

Henry IRVINE bp 09 Oct 1842 (birth given as 09 Jul 1842) son of Robert IRVINE & Mary ELLIS bp Drumkeeran but resident in Dooraa.

I have 2 other children for them - both bp Drumkeeran but resident in Dooraa:
Mary Jane b.28 Jul 1837 bp. 03 Sep 1837
Ann b.22 Jul 1844 bp.28 Jul 1844

Here's the kicker - I found this info before I keep source notes (I used to think "oh, I'll remember where I found that" - I don't - that was a big lesson to learn).
I'm confident the info is correct, but I can not pass the source on to you - apologies.
However, this should narrow down your search so that you can source it yourself.

Robert IRVINE married Mary ELLIS 23 Sep 1829 in Tubrid Chruch, Kesh - that's from transcription of PRONI. MIC/1/37/1 & MIC/1/37/2 by Graham Armstrong.
