This paper utilizes a corpus of Heritage Norwegian in the US, recorded in two small settlements in Wisconsin. The data display changes in the syntax of speakers over three generations of the same community in that specific operations (e.g., the V2 rule) change. Main clause declaratives containing either topicalization or a sentence adverb/negation require the finite verb in second position (V2) in homeland Norwegian. Heritage language speakers typically seek convergence, i.e., they look for ways to accommodate their two grammars with one rule. This often results in the system of one (usually the dominant) language winning out. However, this paper also gives examples of hybrid rules incorporating features from both underlying languages (here, English and Norwegian).
