Hi Heather, my name is Diego Cartledge from Argentina and I´m trying build the Cartldge´s family tree too. The following is the informtion that I have, may be it will be useful for you or ma be you can assist me on this searching.
Thomas August Cartledge married Emily Posner and they had two kids: Bernard Francis Louis(1881) and Mary Linda (I´m not sure about her full name).
Thomas A. Cartledge was a marine steward and was Bernard Francis Louis Cartledge (or Frank Benard)father that was born in February 24th in 1881 in Southampton. Then Bernard has a sister and her name was Mary Linda (I think)
Bernard Cartledge came to Argentina with the trains and got married with Celina Dattoli and had a child called Raúl L.J. Cartledge married with Laura E. Cafaro, they had 2 children: Ana María and Raúl G. Cartledge (my father - 16/06/46-09/10/2004)
