John Kemp (Camp) & Mary Hazelwood diocese of Ossory, Leinster

The Diocese of Ossory covers quite a number of Parishes (about 70) across a number of counties - was the source of the year and location of the marriage a marriage Licence Index ?

If so the marriage was probably in the Established Church (Church of Ireland). Transcripts of some Church of Ireland records in Ossory Diocese are included on RootsIreland (pay-website), but records for many other Church of Ireland parishes are not available online. Quite a number of the original Church of Ireland historic registers were lost in the Civil War. A search of the marriage records on RootsIreland showed no John Kemp/Camp results around 1813, but there were a number of Hazelwood marriages.. 

A more focused search, e.g. checking historic parish records in the RCB Library, would be difficult without a more precise location, e.g. a the name of a town or parish.  Marriages generally  took place in the bride's parish which might help with her place of origin if the marriage could be found.

A search for the surname Camp in the Tithe Applotment Books(*) dated early 1830s, so slightly after your John left, show a small number of results for the surname most in Co. Cavan, the variant Kemp shows a larger number of results also many in Co. Cavan. A similar search for Hazelwood only shows two results - both in Co. Meath.

* the Tithe Applotments were a type of taxation on certain types of eligible agricultural land, and was payable to the Established Church. Not all property is covered by these books.

Co. Cavan is in Ulster Province and most of the county was in Kilmore CofI Diocese, Most of Counties Meath and Westmeath were in Meath Diocese.

Edit : I think I see your John & Mary on the Canadian 1851 census in Carleton - he's a farmer they are both born Ireland both age 60 (born c 1792), with several sons born in Upper Canada. Religion is recorded as Church of England - so Anglican, which is Church of Ireland here.

Another researcher has confirmed that their marriage was in Kilkenny.  ' We know that the marriage was in Ossory diocese – or Ossory, Ferns and Leighlin to give it its full title. It is from the diocese index book which is just a record of the marriage licence.  This covers the counties of Wexford, Kilkenny, Carlowand a bit of Laios.

.  Your ancestor John Kemp came from County Cavan, and there were a lot of Kemp families there in the 19th century. One by one they left or vanished, and now there is only one elderly Kemp man left in the county (and he’s in our project). You know of course that John Kemp and Mary Hazlewood married, and this is their marriage record (it’s actually just the index because the original is destroyed. This is the biggest clue that he is from Cavan because the Kemps there often called themselves Camp, right up until the 1950s, but they’re always Kemp when they move away.  I have other evidence – John and his brother Will are in the Cavan Militia in the 1810s and were posted all over Ireland, including in Kilkenny just before his marriage.  The diocese of Ossory is centred on Kilkenny, so that is where he and Mary married.  And then there is the famous letter that George Argue wrote asking for help with emigration that is published on the Bytown or Bust website – John is mentioned in that, and all the other names with his are also from Cavan.  Will Camp had already gone to Canada before then and is the William Kemp who ran Kemp’s Tavern in Goulbourne.'

I was unable to copy the image of the marriage unfortunately  The title states 'Marriage License Bonds, diocese of Ossory' . 

Ferns and Leighlin are sperate Diocese. Unfortunately the actual Marriage Licence records no longer survive, just some of the indexes you have seen. To establish further details of the marriage you would need the parish record, and to do that you would have to figure out the actual parish and check that historic records are available back to 1813 - not an easy search given the number of parishes involved.  An 1813 Church of Ireland marriage (the most likely denomination) would not provide many additional details - probably just the date and the names of the couple.
