If you extract pedigree names and dates from this chart into your own genealogical database, the correct practice is to include a reference to the source and the researchers involved. This website will continue to be corrected in the light of fresh research, and will, as far as possible, acknowledge each of the researchers who contributed to it. Please copy this URL
into the source or notes field for each individual that you transfer to your own database.


All rights to this website as a whole are reserved worldwide to Jean-Baptiste Piggin. Under a Creative Commons licence, you may copy and distribute certain pages of the website which are thus marked. You may not copy any other pages from the website, but should instead point to this website, either by hyperlinks in your own internet publications or by correctly styled references in your own database or print publications.

You are also permitted to print and circulate loose-sheet copies of any page, provided that the URL and date of download are printed on every sheet (your print driver should do this automatically). However you may not bind this chart in a book, nor deposit it in a library, nor place the file on a website without express permission from me. You must not delete the copyright notice from any copy you make of the file.

These restrictions reflect the fact that all the charts and tabulations are liable to change in future, with all previous versions then withdrawn as no longer valid. The only authorized and canonical version is the one which is currently published on this website. Where manuscripts, photographs and books are presented on this website, you should approach the possessor of the original for permission to re-publish, and may not claim a derivative right through me.

I have granted a Creative Commons licence for certain text pages which are entirely my own work and which I regard as complete. This is my contribution to the public's storehouse of knowledge and I desire these parts of the website to be distributed. Please read the terms of the licence carefully or ask if you do not understand.


This website is a work in progress, the fruit of many people's kindness and interest, and an annotation of where we are after many years of collecting data. If you have a comment or can add another piece to the puzzle, please write to me at the above address. Since the worksheets are largely guesswork, they are bound to contain mistakes - I'm only too pleased to receive criticism and counter-suggestions. Should you feel any information published on these pages is private or not duly acknowledged, tell me too.

And if you only dropped by for a look, do say hello as well: only a few real people (as opposed to search robots) ever penetrate these rarefied reaches of the Internet, so it is nice to know you stopped by.
