You have undoubtedly done a lot of work so its difficult to know what you don’t know already, and therefor I am likely to repeating things well known to you.
I’m at the risk of doing this because in 2004-5 as I was doing my family history from Alton in England where I was looking after 3 children related to my wife with no chance of visiting Co Down, I started a Comber compendium in the form of a a dictionary type index with each townland, village and and last names , even with Comber itself broken into streets , and added townland maps all of which I thought could be added to by anyone else as a side interest which I rounded off by 2008 as I was answering queries on Gavin Wesson free ComberOnline.Org, which sadly disappeared as Gavin moved on in life. Gavin introduced me to Desmond Rainey during 2008 who helped me no end. its now
downloadabe from Comber Historical Society about 30 megabits as a directory of Comber parish. its by no means complete. I still have much to learn now aged 85 !

griffiths valuation includes just
Smyth William Clontonakelly Comber Down which is very disappointing
lateral thoughts sometimes Presbyterians were buried in Church of Ireland graveyards
graveyards exist at Gransha Secessors and Moneyreagh Non Subscribing Ros Davies offers free look up for both and St Marys C of I
Checking the Presbyterian records held in PRONI and listed in their downloadable Guide to Church Records , which might save others repeating

R.C. [Comber parish forms part of the Roman Catholic parish of Newtownards – see under NEWTOWNARDS]
I haven’t listed their microrecords references or their new digital transcriptions under preparation .
comparing the above with listing with Ros Davies Church records, I spotted the North of Ireland FHS (
www.nifhs.org) has Gransha baptisms 1821-1921 & marriages 1822-1921 & deaths 1820-1846 & burials 1854-2000 ;graveyard attached,
you will have searched favourite Co Down website, but I checked under Smith just in case
http://www.rosdavies.com/SURNAMES/S/SmythLW.htm and there are14 matches for Smith did you find anything spelt that way
there are 125 records for Smyth civil births recorded under ‘district’ Newtownards which includes comber see
https://civilrecords.irishgenealogy.ie/churchrecords/civil-perform-search.jsp?etc etc Presumably similar for Smith
I did an index for Comber area in census 1901 and 1911 but didnt get permission to reproduce so didn’t offer to comber society otherwise my interest waned
I never checked for Andrws family records preserved privately or commercial thegirls mentioned might have had jobs within that employer range
good luck onwards and hope you are not caught in the queue outside the PRONI or
https://www.ancestryireland.com which reminds me has free indexs examples to.
