Would like to have a lookup in the book "Middlesex County Marriage & Baptism 1848-1858" compiled by Dan Walker and Fawne Stratford-Devai marriage of John Corsant/Corsaut & Maria Isabelle Fraser. First known child born 1857 in London Township. Corsant/Corsaut family in London Twp 1819. Bride born in West Indies. Thank you, Bonnie
