I am not positive this is the correct Thomas Ingram, but I will tell you what I have and you can see if anything matches your records. If so, please share with me your findings. Thanks!

If this seems as if it is the correct family let me know and I can give you more details of Williams parents all the way up to Sir Arthur's parents.
