Patricia Morrow, Windham Town Historian (Greene County, NY) >Thank you for more info. Her name was Mary A. Hollenbeck, father Joseph, Mother?, born 1845/46 in Oak Hill. She married John Swetland 12/14/1869 in Springfield Ma. That's all I know about her. I been hoping to find her and Joseph somewhere in Greene Co. but so far nothing. Where can I find the 1855 Census? She'd be about 10 yrs old then. Thanks Dottie
