I am currently doing my dads side of the family and they are HARROD's also at one time from Freiston, they might be the same family.
They were in Freiston in the 1841 census
John HARROD b. Dec 4 1794
He married Isabella MARSHALL in Frieston
Children: looks like they were all born in Frieston
Harriett b. 18 Jan 1818 Mark Abt. 1821 William Abt. 1829 Marshall George 24 Jul 1831 Robert Abt. 1834 Francis Abt. 1839
Marshall George HARROD marries Ann Chatterton in 1857 in Boston, Linc
William Richard Chatterton HARROD also found as Willam Howard HARROD. (unsure of name change or why but know that when his son Ernest Chatterton HARROD came out to NZ, he changed his name from HARROD to HOWARD - might have done something naughty :-)) b. 1858
Marries Sarah Elizabeth Sophia RHODES 1881 in Wandsworth, London.
Anyway, he was born in Boston and the other two children after him and possibly others were born in St Olave, Southwark in London
John HARROD's parents were Jeremiah HARROD and Elizabeth WHYATT. He was born abt. 1760 in Rettendon, Essex. He married Elizabeth Nov 1, 1787 in Great Burstead, Essex.
And all his children, can send them if needed: where all born in Billericay, Essex.
So... wondering if your HARRODS are related to mine and would love any info you have. Thinking your David might be say Jeremiahs brothers kids or something. My private email is firstname.lastname@example.org if needed.
