Hi Tracey,
Seeing that I've already helped you with this family, I was curious to see if I could find out any more.
Anyway, here are the females listed on the William Townsend marriage pages (per freebmd).
September Qtr., 1866
William Townsend - Ellen Jones and Elizabeth Sidwell
William H. Townsend - Martha H. Davenport and Anne E. Hopkinson
June Qtr., 1869
William Townsend - Emma Louisa Flintham and Emma Wiles
Those are the only names recorded, but I suppose that William's wife might have been on another page - I have read of that happening in some instances.
Regards,
Richard
