Does Leonardo da Vinci have descendants?

Why this matters here
Because of the slab in the chapel. The remains under it were identified in 1863 by eye and by guesswork, described on this page, and a Y-chromosome comparison with living male-line relatives would in principle settle whether they are his. The descendants have been found. The bones have not been tested. That gap has stayed open for years and shows no sign of closing.
What the researchers did
Working through parish registers, land records and notarial archives around Vinci, in Tuscany, two historians assembled a continuous male line from Leonardo’s grandfather down to men alive now — most of them still living in the same part of Italy, none of them famous, several of them unaware of it until they were contacted. The work has been published and refined more than once, and the number of generations quoted moves around a little depending on which branch is counted.
The honest caveat
A male-line match would prove the remains belong to the family, not that they belong to Leonardo specifically. It would still be enormously more than we have, which is a nineteenth-century novelist saying the skull looked right.
His own line ends with him. He left his manuscripts to Francesco Melzi, the pupil who came with him to Amboise and who was with him when he died, and his vineyard in Milan to his servant. The story of those last three years is on the Amboise page.
If you are here with older children, this is the thread that hooks them: there are men alive in Tuscany who could, with one cheek swab, tell us whether the grave they are standing on is real. Nobody has asked them.
What there is to book
Not the entrance ticket — that is bought at the château’s own desk when you arrive. What is bookable is the guiding, and the day trips that include entry to Amboise along with the other Loire châteaux.
Frequently asked questions
Did Leonardo have children?
No. The traced line runs through his half-brothers, not through him.
Could DNA confirm the Amboise tomb?
In principle yes, through the male line. The remains have never been sampled for it.
Do the descendants live in Italy?
Most of the identified men live in Tuscany, in the region around Vinci.
