Would like to hear from other Ackerman(n) relatives to obtain and share information.

Frederick, b. 1861, was 5th child of William J and Mary Jane Fallon Ackermann from NYC.Charlotte, b. 1861, was one of 5 or more children of Daniel Smith & Sarah Lynch Smith.They were married circa 1880 in New York City (Manhattan, Brooklyn, or possibly Queens). They resided in Manhattan, Brooklyn, and Queens during their lives.

I know ofFrederick & Charlotte’s oldest son, WILLIAM J., my grandfather.I am seeking information on his siblings, my distant cousins:

MARY (b. circa 1880-1884) supposed to have married a Purcell ? - ? of children
CHARLOTTE (b. circa 1884-5) married a Leudesdorf- had 2 sons
DANIEL (b. circa 1885-1887) married a Schultz or Krauss? - had 3 or 4 daughters
CHARLES (b. circa 1886-1890) married a Baynes or Baines? - had 5-6 children, maybe more.
Frederick & Charlotte may have had 2 other sons, a HENRY and a LORENS born near 1900.
