Sorry I've taken a while to reply. I do not have a copy of Louisa's marriage certificate but the records from Free BMD Marriage Index 1837-1915 give the names of Louisa's husband, William Yates, and two other witnesses: Isaac Noyce and Elizabeth Pearce. Reg. Dist. Alderbury, Wilts. Vol No. 5a page No. 259. My cousin has some original documents and states that both Louisa and William had the same surname but may not have been spelt the same way! Louisa's father's name has not come up on any documents so far.
