Hi there,
Thank you both for your replies. The reference to the Lord Exmouth was in Gores Liverpool General Advertiser dated 1826, in the context of an insolvency case relating to Richard Whitford. The pub was in Salthouse Dock, and could have been owned by Ann Jones. So, it's too early for census I'm afraid. I'm sure the pub is long gone, I just thought there might be some records of publicans.
thanks again,
Jan
