Dear Maloney Clonclara/Doonass:
Many thanks for your query to the Ireland Reaching Out message board and welcome to the site.
Unfortunately, the Clonlara parish registers only begin in 1851 and therefore, they are not much use to you.
The marriage register might be of use as that begins in 1851 and it is possible that some of the family may have married before they left. The link to that marriage register is below:
Tradition had it that the bride married in her home parish.
Did you check Griffith's Valuation on the Clare Library website? That might give you a townland where John Maloney resided before he left.
I have had a quick look at the 1852 Griffith's Valuation Transcriptions from the Clare Library. Parts of County Clare that bordered Limerick were enumerated in 1852 while the rest of the County was done in 1855. In your case, Kiltenanlea was 1852. There are several listings of John Moloney, but I note that in the townland of Knockbrack Upper, both Moloney and Sheedys are located. It would also appear that a Denis Sheedy and John Moloney are located there next to one another. This is a very good clue for your research. You can access the original version of the document on the website: http://www.askaboutireland.com/griffith's
The Clare Library website is a good source for other information in the civil parishes and you should check out the other documents or references for Kiltenanlea Civil parish.
You might also note that even though your ancestors name was spelled with an "a", others may have spelled it differently. It is good to keep in mind spelling variations.
If you have not created an Ancestor Profile for any member of this family, please consider doing so under the XO Chronicles tab at the top of the page.
Please let me know if you need further information.
