Francis Alexander Constantine Paszkowski married Emily Parr in London, 1842. He had children, Antonina Alexander Rosalia, 1844, Emilia Constance Paulina, 1846, Frances Alice Julia, 1848 and Francis Alexander Anthony, 1852. Antonina (aka Antoinette) was my great-great grandmother. Does anyone recognise the names, or suggest how I could trace further back as civil registrations don't go back far enough? or where the Paszkowski family came from in Poland?
