JOHAN IV, second son of Gerrit I, and brother of Hubrecht V, was eleventh Lord van Culemborg.  During his brother's life he was Lord of Weerd, and during such period married Barbara, daughter of Lord van Gemen, but did not have any children by her.  His second wife was Aleid, daughter of Arndt van Gutterswyk (ped. 96), Count of Bentheim, and Mechteld van Reifferscheid.  Aleid was sister of Everwyn van Gutterswyk, Count of Bentheim.  According to Zweder van Culemborg, Aleid was obtained in marriage in the following manner:  "It happened that after his wife's death that Lord van Gemen was to marry the Count of Bentheim's daughter, and asked Jan van Culemborg, his brother-in-law, to visit him, which he did and saw the Jonkvrouw on behalf of van Gemen, who said to him, "why do you keep talking of Jan van Gemen, speak of yourself."  One day when they were together he took her upon his horse and carried her to Weerd to his castle, kept her there and married her."  By this wife he had three sons and four daughters.
