You are getting more close to home woohoo !
I also found this, and looking at the genealogy where the last names Bos and Kok and the zeedijk are mentioned as well it might be interesting or perhaps help as well.
Erve Rutger Wouters or Mastenbroekererve
Dijkboek zeedijk: no. 172 Mastebroekererve 14 dm.; no. 178 Huskampien gr. 4 dm.; no. 183 3 dm. Hansenland; no. 187 Hansenweijde 4½ dm. en Groot Hansenland 3 dm.; no. 194 zie 178; no. 195 de kamp 3½ dm., de huiskamp 4½ dm. en 2 dm. op de graft; no. 199 Symon Egbertsgoet 5 dm.; no. 206 Bossiesweijde 4 dm., no. 208 Buurter of Bossiesweijde 2 dm.; no. 214 Bossiesweijde 3 dm.; no. 220 't Hofflant.
1697-1713: Het Eccleastique Rentambt van Vollenhove ontvangt p.j. een uitgang van 4 kop boter uit Bossiesweijde oock gen. halve Reynsweijde in 4 percelen t.l.v. Goltbeeck, Hend. Bloems en broers, Jacob Meinen en Dirck Jans; betaler in 1697 op Martini Jan Jansen; in 1709 Meine Harms Broer
What it shows it there apparently were pieces of weide land (for cows? they had to pay rent and the rent was butter it says 4 cup of butter etc and sometimes how much this was in Caroli guilders) all named Bossiesweijde so maybe that's where the name came from ?
The name Kok also is mentioned: 1785: dbno. 172, 183, 187, 195, 214: Dirk Dirks en Jacob Kok
Anyway, my guess is the family or some of his ancestors (parents/grandparents) probably lived here somewhere and ''pachten'' rented these Bossiesweijdes weideland (meadow ?) and were farmers or at least had cows and were producing (besides perhaps milk, cheese and other products) butter. The butter was also used to pay the rent or pacht .. perhaps they also had a farm or house that was named Bosch.
There are some Bosch and Kok people mentioned, so I think there probably are some members of your family/ancestors mentioned..
Looking at the info from the genealogy and reading it a bit better, they did own a farm and land and at this zeedijk :P
