Looking for information on the parents and children of William Walker (1809-1878)and Mary (?)Walker 1808-1871.I know this much: William died May 17,1878 Mary dies Nov 5 1871. Both are buried at Oak Hill Cemetery in Milford. They were my great great grandparents. Their son James Fredrick Walker and Catherine Marshall Etter Walker are my great grandparents. I have birth and death information for Catherine and marriage records but have NO death record for James. Need death record for James and information for William and Mary. Have no maiden name for her and no parents for either.I Have used the website for Nova Scotia vitals and can NOT find any of the three....and can not find a obit for any of them. Any suggestions?
