Yes, I have discovered that the hard way. I thought I could find the Spake family in the 1850 Chippewa Twp. Census, but the page for Dewlling 115 is out of place. And of course the spelling for the family is not the correct spelling, so I thought I would just browse all of Chippewa Twp., after 2500 people, I gave up for the day. I will go back to it at night, when I have quiet. It is rather sad, that the cemeteries were disturbed. I hope people realize what has been lost and never do it again. I live in Portland Oregon, and we have a pioneer cemetery in town, that every kid in town, seems to think is their own play ground, knocking over head stones, some will never be replaced. Not to mention, in the same cemetery, the City of Portland, paved over a portion of ground, for a parking lot for their building. About 6 months ago, it was discovered that they paved over many graves of Chinese imigrants. Most were buried the turn of the century. Now they have to dig up the pavement, and try to locate each and every grave, and mark it!!!
