A lot of years ago, when I began researching our family name, I thought all the Vandegrifts were probably related some way. I thought some took the name Vandegrift, some took Vandergrift, etc. I knew there were various spellings. Our name was misspelled all the time and so I began recording all names with similar spellings. Over the years it resulted in locating a lot of information – too much to try to put on a web page.
Finally, I have seen enough documents to decide that we are descended from the original family.
