Dear Anne, My earlier info was incorrect. I went to the research centre yesterday and found the following family links:
Daniel Penman: married Matilda Lane on 9th Feb 1820 at Strood, near Rochester.
Their issue was: 1. Maria Matilda, bpt 24 May 1820 2. Mary Ann, bpt 17 Nov 1821 3. Daniel Thomas, bpt 13 Nov 1822 4. William John, bpt 3 Feb 1826 5. John Dalrymple, bpt 15 Oct 1828 6. Gabriel, bpt 2 Jul 1837 (All bpt at Gravesend, St George)
Maria Matilda married William Henry Downer (1820 - 1891) at St Anne's, Limehouse in 1845.
Sorry for earlier incorrect posting. (My Family Tree Maker is playing up)
