Welcome to the Deall family!Sorry I haven't got back to you before now but I've been quite ill for a while. Sarah Deall was the daughter of Thomas Deall and Jane Bonney or Boney and was born abt. 1748 in Sunbury-on-Thames, Surrey, as were her two elder siblings, Thomas 1746 and William 1747.Her four younger siblings were born in Egham, Elizabeth Abt. 1750, John 1752, Samuel 1755 and James 1757.I am descended from James as you are.I do have quite a lot of info. on the Dealls.
