A document recorded by Jean (?) Frossard, notary at Moudon, 22 jun 1739, relates that Jaques François and Jean Jaques Dutoit, brothers, of Neyruz, settle their joint inheritance from the testament of their late brother Isaac probated 07 oct 1736 at Moudon. The testament itself has so far not been found. However, there is a notation that an inventory was prepared 11 feb 1737 (Daniel Antoine Jossevel, notary at Moudon). Heirs mentioned by the latter notary include Jaques François and Jean Jaques Dutoit. But apparently identified as living 03 mar 1738, as joint owner of property being exchanged by Jaques François Dutoit (that reference could have been intended to read "heirs of" his brother Isaac Dutoit).
