I believe Cecilia's father is a Jeremiah Fives, her mother is a Catherine (but I have no maiden name yet). I'm not certain which one though, as there are a few, at least two of which landed in NYC. Jeremiah is either the son of Timothy & Mary or Jeremiah & Julia. Cecilia's birth I believe was Nov 28, 1903, and in the 1910 Census has a younger sister named Catherine. I'm looking now at my printout of the 1910 US Census, and going on the immigration year & that it is a Brooklyn address (the other Jeremiah I have is at a Manhattan address), my guess would be Cecilia's father Jeremiah is the son of Timothy Fives & Mary Cadogan who also came to the US with their kids in 1889.
Timothy's (born 1832 Sep 22) father is a John Fives (who I believe is also the father of Jeremiah Fives, the father of the other Jeremiah in NY). I have a photo that my grandmother said is her father and what she believes is his 'cousin Jerry'. I kind of wonder then if it is that Jeremiah. My great grandfather is a Michael Fives. All the Fives are from a small fishing village, Scilly, Kinsale, Ireland (well, all these Fives. There is a Fives branch from County Waterford as well, that I'm not sure how they may be connected to the Kinsale Fives). It seems like most of the Fives in the NYC area around 1900 though were the Kinsale Fives, and most seemed to immigrate between about 1885 and the early 1900s. Timothy's mother is a Joanna Harrington, and I have no certain dates on John Fives & Joanna Harrington.
I have tons of Fives/Kinsale info, it's become an obsession/passion/etc of mine piecing together this family/town. My grandmother was also born in NY, a Fives, and not just her father, but her mother as well were born in Kinsale.
