It has been some time since writing this board.
My interest is Mary Ann Ody b. abt. 1805, and sister Lucy b. abt 1811 Mary Ann married Robert Bark in London in 1832.
I think that Lucy did not marry , since I have her on both the 1861 census in Toronto and the 1850 census in Pennsylvania (on the way to Toronto) with her sister Mary Ann Bark. Lucy's ages on both censuses agree with birth in 1811.
I found an 1841 census with Lucy age 30, in Malmesbury, Parish of St. Pauls living with mother (I think) Mary age 60.
There also seems to be a Welsh connection because on the 1841 census in Pontypool, Sarah Bark & Charles Bark, children of Mary Ann Ody/Robert Bark are living with Ann Oddy and sons her John & Edwin. I am presuming that Ann Oddy is somehow related to these children.
