I don't know if it is much help, but I have a YERBURY pedigree chart that covers the period you are interested in. There are a couple of MEREWETHER families that married YERBURYs.
Edward (1585-1648) and Anna (Southby) Yerbury
eleven children:
Edward, 1616
John, m. (1) Jane Merewether
Robert, 1623
William, 1620
Richard, 1634
Elizabeth
Ann, 1618
Jane
Honor
and Eleanor, who m. Dr. Alworth, "Chan. to the Bp. of Oxford." They had a daughter,
Jane, who m. Dr. Merewether. Children are not listed for them, but in brackets is noted: (The family of Serj. Merewether.) Whether this means that Dr. Alworth is name "Serj---," or his father was "Serj.," I don't know.
The YERBURYs were a very prominent family at Trowbridge. They were in the cloth business. Edward Yerbury, the father of the above children, was a Commissioner for King Charles I.
My interest in YERBURYs is a daughter of Richard, named Mary, who married Ebenezer Ledyard 24 Feb 1697 at Bromham, Wiltshire, England. I have no other information on Mary Yerbury.
