1849 marriage: Charles Welland to Caroline Morgan by Rev. Charles L. Courtenay

[Rodney53]

I have attached a marriage notice from the Belfast News-Letter, dated December 11, 1849 which names these three people. The wedding took place in Dublin, where the Morgans lived. It also indicates that Rev. Courtenay was the bride's brother-in-law.
My understanding is that Caroline Morgan, daughter of Alderman Lewis Morgan (1784-1832) and Caroline (nee Murdoch), had three sisters, Catherine, Letitia and Jane, none of whom was married.
I am hoping for some help to shed light on who this Rev. Courtenay was, and why he was described as Caroline Morgan's brother-in-law.
Any and all help will be greatly appreciated.
With thanks.

It says Charles L Courtenay but I wonder if it should be Charles S Courtenay.
You can see his signature on the marriage here. (and an address if someone can read it)

Found this online by googling 'charles seaver courtenay'

The Reverend Charles Seaver Courtenay was Thomas Edgeworth Courtenay's first cousin as his father, Henry Courtenay, was the elder brother of Thomas Edgeworth Courtenay's father Charles Courtenay; their mutual grandfather was Edward of Harrymount.

This probate record states his daughter was Caroline
There is a baptism record of a Caroline COURTNEY on Jan 06 1838 in Ballymacgarrett, Co. Down
Parents Rev. Charles S COURTNEY & Maria KING

They also had
Charles Seaver Bap. Nov 15 1835
Joseph John King Bap. Jun 14 1840
Catherine Elizabeth Seaver Bap. Apr 02 1843

To be "the bride's brother-in-law" he would be married to her sister or her husband's sister
As she was a spinster when she married would rule out the latter.

Rev. Courtenay could have been married twice
He died in 1865 aged 59 which implies he was born c1806

I think that the newspaper was slightly incorrect in the connection

Maria KING was Caroline MORGAN's half sister - they had the same mother

Charles Seaver COURTENAY married Nov 22 1827 LINK
Maria KING, only child of Joseph KING, Capt. 64th Regt.,
by Caroline, his wife (she married secondly Lewis MORGANof Dublin)
daughter of George MURDOCH of Belfast, Esq.;
Capt. KING was sixth son of James KING of Co. Fermanagh

LINK notice of second marriage in 1813
and reference to KING family


Joseph KING and Caroline MURDOCH had at least three other children, George, Anne & James
