Hello Penny,
After reading your message, and the replies kindly provided by Carolyn, Eileen and MaryTV, I had a suspicion that Ellen Short may not have belong to the Catholic Church, at least, not in England.
Based on your information that Ellen and James Robert Ruff were married in Westminster, London, on October 20, 1850, I looked for a copy of their original marriage record to see if the marriage took place in the Anglican Church of England.
In Ireland the Anglican Church is the Church of Ireland.
I found the marriage record for Ellen and James at the Ancestry.com subscription website. As you know they were married in the church of St Mary, Tothill Fields (St Mary the Virgin, Vincent Square), London, Westminster, England. This is a Church of England parish, rather than a Roman Catholic parish. So you don't have to dig into your files, the marriage record is attached to this reply.
This means that Ellen may have been baptized in the Church of Ireland when she and her family lived in County Louth. RootsIreland has not transcribed Church of Ireland baptisms, marriages, and burials for County Louth.
The challenge for genealogists and family historian with Church of Ireland ancestors is that almost half of the Church of Ireland parish registers of baptism, marriage, and burials, were destroyed in a fire at the Public Record Office, Four Courts Building in Dublin during the Irish Civil War in 1922.
But that leaves half the Church of Ireland parish registers that weren't destroyed.
Knowing this I wanted to see if the Dundalk, County Louth Church of Ireland registers survived the fire.
To do this I went to "The List of Church of Ireland Parish Registers" website at: https://www.churchofireland.org/cmsfiles/pdf/AboutUs/library/registers/ParishRegisters/PARISHREGISTERS.pdf
Here I found that there are baptism, marriage, and burial records available for St. Nicholas Church of Ireland, Dundalk, Louth.
Baptisms are available from 1729 to 1924; marriages from 1750 to 1929; and burials from 1727 to 1985.
The parish registers for St. Nicholas are held by the St. Nicholas Church of Ireland in Dundalk. Information at "The List of Church of Ireland Parish Registers" website notes that..., "local clergy in both NI (Northern Ireland) and ROI (Republic of Ireland) are...obliged to make available original registers in their custody available under both national legislation and in accordance with the Constitution of the Church of Ireland."
Penny, I suggest sending an email to one of the St. Nicholas Church of Ireland clergy to see if they can look for Ellen Short's baptism in the Dundalk registers. Mention you cannot come by the church because you live in Canada.
You can send an email request for a search of the parish registers to one of two clergy members in the Dundalk parish. One is the Rev. Shirley Murphy, who is the Rector of the church. The other clergy is the Rev. Richard Moore, non-stipendiary minister.
You can find their email addresses here: https://www.armagh.anglican.org/Parishes/DundalkHeynestownUnionBallymascanlanUnionCreggan.html
Also, because you do not know the exact year of Ellen Short's birth (her marriage record states she was "of full age,"), and because Church of Ireland babies were not always baptized within a short period of time after they were born, as Catholic babies were, I suggest giving the date of Ellen's baptism between the years 1820 and 1832. The year up to 1832 because Ellen would have been 18 years old in 1850 when she married if she had been born in 1932.
You'll also want to provide the name of Ellen's father, Michael, who may have been a soldier when Ellen was baptized. You'll also want to mention that you do not know the first or maiden names of Ellen's mother.
The other thing to be aware of is that Church of Ireland and Church of England baptism records traditionally provide the name of the child, the first and sometimes middle name of the father, the surname of the father and child, and the first name of the mother, but not the mother's maiden name.
I have seen however, some Church of Ireland and Church of England baptisms where the maiden name of the child's mother is recorded, but not in the case of the September 3, 1851 baptism of Sarah Jane Ruff, found at Ancestry.com.
Sarah Jane's father is James Robert, and her mother, Ellen. Ellen's maiden name "Short" is not recorded.
The baptism took place in the St Mary, Tothill Fields (St Mary the Virgin) Church of England, Westminster, London. The baptism record also shows that Sarah Jane Ruff was born on July 29 1851, and that the residence of the parents was Russell Place. James's occupation was "Bricklayer." The baptism record for Sarah Jane Ruff is attached to this reply and is indicated in the register by the green arrow.
Also attached to this reply is the July 15, 1853 St Mary, Tothill Fields Church of England baptism of Alfred Charles Ruff, son of James Robert and Ellen Ruff. Ellen's maiden name is not recorded.
Alfred Charles was born on 19 April 1853.
What this means is that if you send an email to one of the St. Nicholas Church of Ireland clergy, you'll also want to request a look-up for the marriage of Michael Short in the St. Nicholas Church of Ireland marriage registers, as the marriage record will provide the full name of Michael's wife.
There is a small charge for research into the parish registers as you can see in the fee schedule here: https://www.armagh.anglican.org/Contacts/GenealogySearches.html
The fees are in Euros and I believe Northern Ireland Pound Sterling, but you can ask if you can pay for the records by credit or debit card.
If for some reason you do not hear back from a clergy member, or if Ellen's baptism record isn't located in the church registers, please let me know and I'll see if there are other avenues of research you can explore--perhaps a search of the Newry, County Down Church of Ireland registers, which also survived the Four Courts fire in Dublin in 1922.
The St. Nicholas Church of Ireland is a very old church, with origins dating back to the 1400s, though there have been many renovations over the years. For more information about the church, go to the National Inventory of Architectural Heritage/Buildings of Ireland website link at:
