btw, I forgot to mention another family chart which is probably related to Wolterus and Johan:

Albert Hagewolt, the deputy mentioned in another reaction above, deputy of Drenthe to the Archduchess in Brussels 1621, etc., married Engeltien N. They were parents of :

Herman Hagewolt, born about 1595, kerkvoogd te Meppel 1618, Landdagscomparant 1619, twaalve van Meppel, died 1627 at Meppel, married June 13th, 1619 at Havelte with Anna Struuck (Struik), who died in 1681 at Meppel, who was a daughter of Gerhard Struuck (of Overcinge near Havelte) and Mechtelt van Steenbergen. Anna Struuck remarried with another ancestor of mine, Joan Albert(s) van Bonnema (via their daughter .

Herman and Anna had at least one daughter, Engeltien Hagewolt, who died October 29th, 1703 at Meppel, who married in 1646 with Mr. Wolter Sichterman (1620-1678, who was a brother of another ancestor of mine, Ds. Gerrit Sichterman 1618-1672 who married to Anna's daughter Wilhelmina van Bonnema -1700).

Did Herman and Anna have more children, a son??! Wolterus Haagwolt was born about 1645 so might be named after his uncle Wolter Sichterman? Then the/my puzzle would be complete!
