My Great Great Grandfather is also William Matchet Landis and my Great Great Grandmother, Sarah Winters, My Great Grandfather is Edward Landis, (is William and Sarah's(one of three I have on 1860 Census) and Great Grandma Martha Allen Pontious his wife. and Ira Joseph Landis, my Grandfather, Son of Edward and Martha Landis. I found Williams Matchet Landis's parents on Grave Finder. My aunt who has passed away a while back had found Samuel and his children but for some reason didn't have his wife. But me and my daughter had found them both with the death dates and location, we found on Grave Finder, Samuel's Wife is Elizabeth Stretch. That is as far back as I have gotten but on Family Search, it goes back even further, but I want to find records to verify that they're correct. Still want to find more on Samuel and Elizabeth to make sure that these are the correct one. I am attaching photos my mother had of these people. William looks just like my eldest brother. Ha Ha
