Some secondary sources show this Ann Lakeman having married William Newland [in Dodbrooke] in 1825 before emigrating to South Australia in 1840. However, the SA records* show Ann Newland died in 1881 aged 81 years (b.c. 1800), and Ann Mary Jackson Lakeman's parents weren't married until 1803. To-date no record of another Ann Lakeman born c.1800 has been found, though she may have been the daughter or sister of Thomas Lakeman who was one of the witnesses to her marriage.
