My husband's ancestor is Robert Quirk b 1819 Liverpool ENG, son of William Quirk and Jane Ellison., grandson of Phillip Quirk b Ballaghver German IOM c 1727 and Mary Parr.

Robert married Mary Allgood RADCLIFFE on 14 Feb 1843 at "St Mary, Walton" wherever that may be.They had several children between 1843 and 1848: James Radcliffe , William Augustus , Helena Sarah and Robert Frederick, all of whom I have found births for.
However the last child, Malvina Christina QUIRK born circa 1849 is a mystery. I can not find any record of her birth.
Robert senior came to Australia after Mary's death in 1854 at Wigan ENG. He remarried here and states that he is a widower with 3 children. However it appears only Malvina came with him

The mystery is, which, if any, died and what happened to the other children who seem to have stayed behind.
On Robert's death certificate in 1902, Malvina is listed as the first child of the second marriage. Her grand-daughter was sure she was born over seas and came out as a little girl.

Are you familiar with any of these Quirks?
