Two of the daughters of William Acre Sr who died 1688 in Lancaster Co VA were married in nearby Richmond Co VA
Katherine Acre (Acree/Ackers/Accus) married William Percivall before June 19, 1714 Richmond Co VA
Elizabeth Acre married Cormack McCarman before June 19, 1714 Richmond Co VA
Both marriage records indicate that their brother William Acre Jr was deceased. I am wondering if June 19, 1714 was the date of his will. He would have been 34 years old, so could have had children. Still trying to get a lookup in the book Wills of Richmond County VA by Robert Headley. If I can't get a lookup I will try to find the book.
The marriage records are from another book by Robert Headley "Married Well & Often: Marriages on the Northern Neck of Virginia". Excellent book!
