Not sure if you're in UK or USA, but my Kingsbury's were born in Kent in the UK. Specifically, places like Pembury, East Peckham, Tonbridge, Withyham, etc.
Does this ring any bells? Do you have any connections to Ripon? (some did move to other places, but this was the starting point out in America).
I currently don't have an Ancestry subscription, but I have this board marked so they send me alerts - so I'll get any further posts you may leave. Hope to hear from you.
