There seems to be some uncertainty as to whether the Richard Tydings in Maryland is in fact the same Richard Tydings born May 29, 1625 in Stepney, Whitechapel, London, England.According to the International GenealogyInstitute, the parents of the Richard Tydings from England were listed as John and Margaret.
As to the Richard Tydings/ Charity Sparrow association, it is my understanding that Richard married Charity Sparrow about 1658. Although I have not personally viewed the document, it is my understanding that Richard witnessed the will of Thomas Sparrow in 1675.
Richard's will, dated February 2, 1687 , names his eldest daughter Charity as executrix. Charity was named after her mother, who was already deceased by the time the will was written.
