my apologies for not explaining it, bbb is shorthand for birthbestbefore and is a way of forming generations with unknown facts. Where I have used bbb I am taking 15/16 off the birthdate of a child,and in your case a marriage to find what decade in that century, I should be looking for ancestors going backwards..
the tithes are full of questions and the best explanation for you is to look up an original
Montford entry in the 26 counties version via nationalarchives
http://titheapplotmentbooks.nationalarchives.ie/search/tab/index.jsp the montfordhave which has a copy of the original attached unlike NI which is a simple name index done by the Irish Genealogy hub, not by PRONI staff
the index opens with two entries for Archibald Montford the first entry is
http://titheapplotmentbooks.nationalarchives.ie/reels/tab//004587398/004587398_00128.pdf which shows an entry No 414 for Archibald Montford as townland owner
and then the 2nd entry is
http://titheapplotmentbooks.nationalarchives.ie/reels/tab//004587398/004587398_00137.pdf which shows which shows the same entry No 414 for Archibald Montford as townland owner
I think this shows the index has been done from the microfilm records by possibly two different indexers but its the same entry,and same person
I tried another with two entries for a henry montford which has two entries but this time separate townlands in Killashee Longford 1835
http://titheapplotmentbooks.nationalarchives.ie/reels/tab//004625671/004625671_00232.pdf shows henry montford has 20 acres of deep soil and 23 of moor pasture in total taxable value £2 6 shillingsetc in Ballycore
the 2nd entry is for a different townland but with same microfilm reel number there is no way of telling if it is the same henry mountford he has a plantation this time.
all this suggests the Northern Ireland files have been produced not from the originals but from the microfilms. I use the tithes for 1. their location value in finding further possible information under local history rather than family history.2 the other same names in the townland or parish who might be relatives. THE PRONI Belfast is currently producing a digital version on the tithes which will help those who cant travel enormously
back to the list
Munfoad, John Townland: Loughconoly Year: 1825
Munfoad, John Townland: Loughloughan Year: 1825
Munford, John Townland: Loughconoly Year: 1825
I separate them into separate townlands
Munfoad, John Townland: Loughconoly Year: 1825
Munford, John Townland: Loughconoly Year: 1825
Munfoad, John Townland: Loughloughan Year: 1825
my guess is in Loughconoly and some time during his visithe has discovered its spelt another way so its probably the same person
so better than nothing the tithes were collected not for the government but for the church of ireland and then collected by the government for the church. Somebody has probably written a book about it.
good luck
