This is what I have:
John Daines (d.1819 age 60) married Ann Saward (d.1801 age 30).
Their son John Daines (b.1793 d.1863) married Susan Reynolds (d.1889 age 92).
They had 9 children: John (Saward?), Thomas, Edward, Agnes, Ann. +[William, George and Sarah Ann-died young]. Ann never married. Edward emigrated to New Zealand. Thomas emigrated to South Africa (on the mail ship RMS Dane). John and Agnes ??
Thomas Daines (b.1832 d.1877) married Anastasia Warren (b.1837 d.1921) [was she Jane Warren’s sister?]
They had 8 children: Thomas Martin, Edward Warren, Walter Reynolds, Agnes Mary, Henry John, Ida Mary, Annie Caroline and Rose Constance. [Walter, Henry and Rose died young]
Thomas Martin Daines (b.1864) married Kathleen Jacoba Devenish (b.1875).
They had 5 children: Gerald Martin ST Leger, Ivan Robert, Norman Walter, Victor Maximillian and Iris Kathleen.
Norman Walter Daines (b.1908) married Jean Park Muir (b.1904).
They had one child: John Muir.
John Muir (b.1938) married Janet Donaldson (b.1942)
They had 2 children Thomas Gordon and John Robert.
That is me- John Robert Daines (b.1977).
I had some of what you supplied, but I did not know that Edward(NZ) had first married Jane Warren. I have a photo of Edward Daines (b.1837). My father did most of the research I have, so I may have some facts wrong, but I doubt it.
If you find anything more on John Daines (d.1819) and his parents please let me know! E-mail firstname.lastname@example.org
