Where are you?

I'm looking for more information on Caroline Estelle Ward b about 1874 in NY and her family.  She married Frank Coonradt sometime after 1900 and they had a child, Gertrude, born about 1906.  By 1910 Caroline is a widow. 

I also would like more information on Nellie Emeline Ward b Oct 1875 in Berlin, NY.  Supposedly she married Frank Krueger.  I can find no information on him or Nellie other 1800 and 1900 census for Nellie.

Myron Ward, a brother for the two listed above is also elusive.  He was born Ag 1883 in Berlin, NY.  Did he marry Gertrude and move to Glen Falls?

Abby Jane Cook b abt 1859 NY, probably Rensselaer County. I am assuming she married by 1880 as she is no longer listed with her mother on the census.  Who did she marry? Where did she live?

Hattie L. Cook b abt 1879 NY, probably Rensselaer County.  Found her on 1880 census and that's it.  Anyone know anything about her?

Amanda M Cook b Sep 20 1856 married a man by the name of Walker.  She died in Vermont.  Who did she marry? 

Levi Cook b around 1850 in Rensselaer County, NY.  He married Mary Lawler.  What are their dates of birth/death/marriage?

Sisters Susan (b abt 1847) and Lovina (b abt 1848) of Rensselaer County, NY are also lost.  Can you help me find them?
