Finnerty and Callon families in Peterswell, Gort, Loughrea

I've just had what may be a big breakthrough in getting past a brick wall with my family! But, I need some help solidifying a bunch of circumstantial evidence to see if these families really are connected...and...hopefully...find some cousins in Ireland. Specifically, I'm looking for Ellen Harte in Peterswell; Mary Coen in Loughrea; and Thomas Callon in Loughrea, all around 1933.

If you want to jump to the end, I'm looking for information about the people listed in the legal notice posted below. I believe they are all part of the Callon family. But, to set the context, here is the information that led me to that legal notice:

(1) Martin Finnerty and Bridget (Delia) Callen, from Peterswell, were married in Ireland. They came to the US in the late 1800s and settled in New Jersey. They didn't like it there and decided to head back to Ireland.

(2) On the voyage back to Ireland, my great grandmother, Kathryn Augustine Finnerty was born aboard the SS Baltic on 23 Apr 1888. I believe the family, at that time, would have been Martin, Bridget, an older sister Mary, and Kathryn. They made their way back to Peterswell.

(3) Martin and Bridget had several other children: Patrick J (1890), Ella Josephine (abt 1891), Anna Marie (abt 1895), and Joseph Michael (26 Feb 1897). I believe they were born in Peterswell, but they seem to list Gort, Peterswell, and Loughrea interchangably.

(4) Bridget died 12 Apr 1900 during childbirth in Peterswell (I have a record in the Calendars of Wills and Administrations that confirms this). At this time, Martin was a farmer and shopkeeper.

(5) "A relative" in New York sent for the oldest, Mary, to come to the US. Mary was in love at the time and didn't want to leave Ireland, so Kathryn Augustine went instead. She was 16 at the time.

(6) In 1904, when Kathryn arrived in New York, the ship's manifest listed her final destination as "Aunt Mrs. William O'Brien" at 317 Gorham Street in Canandaigua, New York.

(7) The 1911 Canandaigua Directory lists Michael Callon living at 317 Gorham Street with his wife Mary.

(8) Joseph Michael Finnerty lists his home address, on his WWII Draft Registration in 1918, as 317 Gorham Street.

(9) The legal notice below, following the death of Michael J Callon, lists a lot of family members, including: Ellen Harte in Peterswell; Mary Coen in Loughrea, and Thomas Callon in Cahercra [I'm guessing this is supposed to be Caherlea?]. The key thing to note is that the notice also lists Joseph Finnerty in Detroit; based on the address listed, I know this is the same Joseph as the one listed in #3 above. My theory is that Michael (the deceased), Ellen, Mary, and Thomas are siblings (or some other close relation) to the Bridget Callen/Callon that married Martin Finnerty. But, I need help tracking them down in Ireland. I'm hoping that these 3 additional names and locations in Ireland will help figure this out.

As you can see, the connection is still very circumstantial, but it's feeling like I'm on the right track. Bridget Callen [Callon] was from Peterswell; her daughter Kathryn was going to 317 Gorham Street in 1904, where Michael Callon is living in 1911. When Michael Callen dies, he lists Joseph Finnerty at the same exact address in Detroit as is known from other records. And there's the bonus of other family members in New Jersey, where Martin and Bridget supposedly settled when they came to the US.

Any thoughts or suggesitons on where to search for this information would be greatly appreciated!
