I am researching William Hallett born abt 1815 father William, farmer. Born in London. Don't know if married twice but to Emma Matilda Stevens (second marriage, first marriage to Charles William Schnitzler) in 1840 in West London. Would like to find Williams parents, if he had children. I have that he had Georgiana, William Robert, and Eliza Jane. Emmigrated to Australia on the Bangalore in 1854. Cannot find where the children were born. Hoping for any information.
