Bigmamashouse,
Rebecca O'Connor, Thomas Byrne and Joseph O'Connor are not part of the Seamus O'Connor family tree - as far as I can tell.  Seamus O'Connor's father was Thomas O'Connor (b 1852 - d 1936), his mother was Sarah Reilly (b1861 - d 1924)  The address you provided when replying to the Seamus O'Connor post also did not match any addresses in the family history we have to date.  Does this help you at all?  MattieMae

Aileen,
I am in touch with Dan McGill.  His eldest daughter lives about 30 miles from our youngest daughter in Oregon.  Both his other children are alive and well.  He has been sharing information about my grandfather (amusing stories from his childhood) with me.  I am also in touch with another cousin, Terry (who traveled to Ireland with Dan for the family reunion in 2000.)  Looking forward to hearing from you.  Your cousin,  MattieMae

Aileen,
Seamus O'Connor was the eldest of ten children born to Thomas and Sara (nee Reilly).  He was born in 1882, Newton House, St. Margaret's Nth, Co. Dublin and died in 1960, Howth Road, Dublin 3.
When my grandmother and her cousins stayed with him on 7 Hollybrook Road, Dublin, in 1947 Seamus was the Sheriff of Dublin.  My grandmother's letter dated July 25, 1947 said he was attending a garden party with De Valera.  Other letters shared the day to day life in Dublin at the time (post-war), strikes and much more.  Our cousin, Marie, traced the family back to 1771 and presented the book to family member attending a reunion in 2000.  I did not know about the reunion or I would have been there.  Marie shared a copy of the book with me.  I've added more information and made corrections to the information (as was intended by Marie).  Do you want the names of Seamus' sisters and brothers?  I don't have information on His father's family but David probably does (dabirchall).  I have the history of the O'Reilly family.  Hope some of this helps.

Salome,
My grandfather and Seamus' mother were brother and sister.  I would be Fionnghuala's second cousin.  Seamus' mother was Sara Reilly (1861-1924).  I grew up sharing much of my early life with the O'Connor's (Seamus' sisters) who lived in the San Francisco area of California, USA.  I have many pictures of them (including one taken at my wedding with Anne, Sally and Bridget) sitting side by side.  They are all buried at Holy Cross Cemetery in Colma, California.  My records of Seamus' family shows six children:  Sorca Marie (1912-1974), Fiacra (1913-1933), Fionnuala (1915-1995), Colm (1920-2002) Caoimhe (1922 -1926), Eibhin (1924-2003).  I have the names of two of Fionnghuala's three children.  Are they all still living? I am interested in any information you have that you would like to share and would be happy to share what I have or do research for you. David, who you directed your first reply to, is a direct descendant of the O'Connor side of the family. He is very interested in researching and sharing his family history, too. 
There was a reunion of the family held in 2000 in Dublin and a book of family history written by our cousin, Marie, was shared with all in attendance.  If you are interested she has offered to send you the information she has about your part of the family history. She would need an e-mail address to send it to.  Mattie Mae
