I am seeking information on my great grandfather's sister, Emma Frances Tracy, who married a Thompson and lived in Fulton County, Illinois in 1873.  She was listed on her father's probate record.  I know she was born 11 Dec 1851 in Lowell, Middlesex, Massachusetts to Timothy Nutting Tracy and Hannah J. (Bean) Tracy.  Her brother, my great grandfather, was Fred Walter Tracy born 10 Sep 1853 also in Lowell.  I have tried the censuses to no avail.  I do not know her husband's given name but wish any information on him and/or her that can be provided.  Thank you for any help you might be able to supply.
