He was the father of Clifford Burns and grandfather of Charles Montgomery Burns. Wainwright forcibly adopted him and is responsible for transforming from a carefree boy into the miserly old man he is now so often perceived as. Many of Charles Montgomery's cold-hearted characteristics are noticeable in Wainwright as well. It has been referenced that Wainwright directly destroyed Charles Montgomery's innocence (it may even have been Wainwright who gave Charles his own middle name "Montgomery" in the first place).
