Excellent work and well documented. However, y-dna has now proven that Samuel Hillhouse/Hillis, Sr. cannot possibly be a son of John Hillhouse of Freehall who was a son of Abraham Hillhouse of Scotland.
The proven male descendant's of Samuel Hillhouse/Hillis, Sr. is I1. The proven descendants of James Hillhouse, proven son of John of Freehall is I2b1. So this information cannot be true regarding Samuel Hillhouse, Hillis, Sr.'s origin. That remains unknown.
Additionally Martha Hillhouse/Hillis is not a daughter of Anne Luckey in that Samuel Hillhouse, Sr. and Ann Luckey were not married until after 1747 and in Martic/Lancaster/PA. Martha Hillhouse was born at least 10 years before Anne Luckey married Samuel Hillhouse, Sr. Anne Luckey and Samuel Hillhouse did have a daughter named Martha but she was born in 1761.
