You are fortunate to have found a Census that says more than Ireland. Baptism and marriage records before 1864 are
Parish record. After 1864 Civil Registration took place and you would see both Parish and Civil Registration. I would imagine they married about 1850, average age 20 for women
25 for men.
Parish records for Co. Clare are not on line. Clare is 1 of 4 Counties who do not participate in an on line Irish History Foundation, fee for service but not for profit.
There is a Clare Geneology Center, see the Clare library but
commission work only. Like most of Ireland you will need to pay for genealogy unless you are lucky enough to come across some records donated by someone who has done the research already.www.genealogy.nationalarchives.ie
The earliest record used as a census substitute (census 95% destroyed)are the Tithe Applotments from 1820-1839 throughout Ireland. Only heads of households are named.
109 Howard's. So will go with the Shorts as its easier to start there.
Parish of Killofin.
Howard: Conor, Michael John
Howard: James x 2 and Richard
Clooney Parish John Short, Patrick Short,Laurence Short & Terence Short
Killofin Parish Edward Short, Thadeus
By the time of Griffith Valuation 1855 there are now 110
Howard's and 8 in Parish of Killofin, names are
James, Edmund, Margaret, Michael, Denis & Patrick
In Parish Clooney 1 Mary Howard. Probably women listed would be widows as rarely is property in a woman's name. If widowed she would need to apply to the landlord to change
a tenancy to her name.
There are Howard's listed in the commercial directories for Clare but no Joseph's.
No Short's in the directories 1824-1894.
Look for names that Joseph and Johannah named their male children. First girl should be after Johannah or her mother, lst. male after Joseph or his father.
Are they Catholic or Protestant? I have a CD with Protestant/Church of Ireland marriages 1845-1862.
these also can be seen on www.familysearch.org
Currently there are technical difficulties or I would have had a look but you can do this yourself.
Marriages just have the bride and grooms father listed.
Parish/Place and date.
