Dear Ken,I was wondering if you could possibly give me some information on my ggg grandparents that are listed on page 225 of the book, "Cemeteries of Brown Co. 1825-1972? They were LEVI & SARAH LUSK. Their daughter ELIZA J. (LUSK) KENDRICK is also listed on p.223. I would be very greatful for your assistance in this matter. I am mainly interested in the name of the cemetery where they are buried and also if it gives the first names of their parents.I know Sarah M. was a Brooks, from KY., and I know the dates of their birth and death, but that is about all I know. I would truly appreciate any information you could provide.Thank you so much, Kathleen from Vancouver, WA.
