Final answer:
The question lacks context to determine the origins of the characters Rubin and Rainie or the specific text or historical period in question, making it impossible to provide an accurate answer.
Step-by-step explanation:
The question appears to be a reference to a specific historical or literary context where characters named Rubin and Rainie claim ownership over a piece of farmland and the rights to hunt on it. Without additional context, such as the title of the work or period of history being referenced, it is not possible to provide a factually accurate response. To adequately answer this question, further information would be required to identify the source material and ascertain whether the claim by Rubin and Rainie is historically accurate or a fictional plot point.
