Many thanks for your reply-
Louise or Louisa or Lulu, as she was known in the family, was my Great Grandmother so we are distant relatives.
Since I posted this query I had a reply from another distant relative of this line and she was in posession of the comprehensive family tree for the Whybrow and Cogger families in Kent as far back as the seventeen hundreds. I presume you already have that information-the financial 'fall' of Louise's family etc? if not I can of course connect you to those in the family who have the information?
