Thank goodness it finally worked and you are here at last. Welcome.
I tried Delespine using the Forum search engine and two results came up but in US, although quite an unusual name so may lead you somewhere.I then tried http://www.kuijsten.net/usenet_search/genealogy.htmlhttp://www.kuijsten.net/usenet_search/genealogy.html and found nothing but a search for "lepine" gave a lot of results.
Have a try at that search engine which searches the newsgroups.I will keep an eye out for any other Delespine names in my other searches and let you know how I get on with them.
As it is French would it perhaps be De Lespine?Just a thought, let me know.
