Thanks Alan,
Our Elizabeth Redpath (daughter of Thomas Redpath & Grace of Cargans) married Robert Bennett in 1847 and he died 1849. When Elizabeth (Betty Ann married George Guinea in 1852 the William Whitten the witness we think would be husband to Lucinda (nee possibly Tully) .Elizabeth Redpath and Lucinda were cousins so Lucinda's mystery Redpath mother was a sister Elizabeth's father Thomas Redpath. DNA matches have also been found to support this relationship. We know that William Whitten had died by 1865 as mentioned in his father's will Robert Whitten d 1865 Cargans. Thomas Redpath's brothers were Robert & John and sister Margaret with unknown Redpath sister mother of Lucinda (Lucy) that we know. The other Redpaths you mentioned are possible cousins of Thomas, Robert, John, Margaret & unk sister and we have DNA matches to that other Redpath family too. I am not sure who Elizabeth Redpath d 1876 would be but I am assuming she is the wife of one of the other Redpath family at Cargans as she is not in our branch. Thanks again Alan if you ever discover the Tully/Redpath connection I would be very interested in the details.
