Hi Ann I am searching for info about Sir Thomas Wolstenholme, who married Ann Andrews about 1645 in London. Their daughter Ann married in 1668 Philip Matthews who was granted a Baronetcy in 1662.
I think perhaps Sir Thomas is connected to your Sir Nicholas, but have no further information about him.
Philip Matthews we think is connected to the Matthews family in Norwich, from whom I am descended, though it is believed that the Baronetcy became extinct on the death of his son John at Oudenarde in 1708.
Ideas welcome, Cheers from summery New Zealand, Jo
