Peter HAYDEN or HADEN was born in Ireland about 1815 - 1820. He immigrated to NYC about 1830. He married Mary MALLEN - they lived in the 15th & 16th wards of Manhattan. Known children born to this couple were: Francis (known as Frank) 1844, Ann 1846 & Patrick 1848. Frank Hayden served in the Civil War. He married Annie FAHEY / FAY. She'd been born at Netley Park, Co Mayo, Ireland in 1845 to parents Terrence FAHEY & Hannorah KANE. Siblings were: Patrick, Catherine & Ellen FAHEY - all born in Ireland. Annie FAHEY's mother Hannah also came to NYC, but I've nothing to suggest that her father ever did. Annie's brother Patrick FAHEY also served in the Civil War . The family lived in the East 20s - near 2nd Ave in the 1870s. Later moved further uptown -and eventually to Douglaston, Queens.
