Since this original posting, I have discovered additional records.

In the 1866 obituary of Patrick's older brother, Peter Wrenn, a veteran of the Civil War, Peter is identified as a native of the Parish of Mohill, County Leitrim. An additional obit identifies Patrick as having brothers called John, Peter, James and Michael.

Also found Patrick's marraige record to Ann Murry in June of 1850 at Nativity Church, NYC, where his name appears as Patrick Rinn.

This Patrick "Mac" Wren was born in 1824 in Leitrim to Thomas Wren and Ann Slattery...

Hi Patricia,

Thank you kindly for posting this record. I actually had noted it myself some years ago when I had some credits on Roots Ireland. 

What argues for it as a possibility is that while the Baptism occurred in Bornacoola Catholic Parish, the townland of Drumard Jones is also in Mohill Civil Parish, where Peter Wrenn's obit identifies him as a native of. In addition, Patrick's wife, Annie Murray, was apparently from the townland of Keelagh, also located in Bornacoola Catholic Parish but likewise in the Civil Parish of Mohill.

What makes me sceptical is the father with a given name of Thomas. The known sons of Patrick S.Wren in birth order are William Henry, John Joseph, Thomas, James Edward and Francis Patrick. There could be other infant deaths but the first 3 are certainly the first 3 sons and in the right order. Known sons of Peter Wrenn, Patrick's brother are Peter and John. Known sons of his brother, John, are Patrick and John and possibly Peter. And Patrick S's own death certificate show his parents as Patrick and Ann Wren but since that is the name of himself and his wife too, I'm not sure if the death certificate might be in error.

I have trouble locating the Mohill Parish records on the Tithe Aplotments - I think I have found  some of those records scattered around different counties, and I have written to the Archives about it but received no response.

In Griffiths Valuations, there is a strong Wren/Wrenn/Wrin presence in the townlands of Sratrissaun North and South and Lismodaun, including Patricks, Peters and Johns. These townlands are in Mohill Civil and I believe Mohill Catholic parish.

Either way, I am delighted by recent progress and thank you so much for helping me along.

Best,

Ed

Hi Ed,

I have Wren/Wrenn/Rinn/Ryn/Renn/Rhinn ancestors from Toneywardan townland, Granard, Co. Longford, so your post caught my eye. I'd actually done some research on Patrick S., son of Patrick and Ann, a while back, thinking he might be a relative of my John Wrenn, as he also lived in Manhattan--on E. 29th St. I even have a photo of Patrick S.'s gravestone in Calvary. If you don't have it, I can try to post it on IRO.

Hi Patricia,

My personal Email is erstewart@gmail.com. John Wrenn (Wren) at least one John Wren who lived on East 29th Street was my Patrick S's brother. However, I have an obit showing at least "a" John Wren on East 29th Street was a native of County Leitrim. Also a John Rinn on East 28th Street but also a Leitrim native.

Here is one but I don't believe this one is mine:

Plus his actual obituary:

Let me know if I can help you with clarifying anything.
