Jacob Brown lived prior to 1840 in Crawford Co., PA. Information included in his father's probate file stated that Jacob was residing in Fulton Co., IL in the year 1848, and that he had moved to Fulton Co. about 10 years previous to that time. Can someone check the 1850 census to see if Jacob Brown is listed. I would like to find the names of his wife and children. And, if they died in Fulton Co. Also, are there books available for census, cemeteries, marriages, etc for this county? Thank you in advance, Bertha
