ABSTRACT

This study presents a new method to measure the depth of ancestral roots in a population. This method sheds light on the migratory movements that led to present-day population distribution across space. The method was applied to a dataset of 5,100 ascending genealogies from 17 regions of the province of Quebec (Canada). Dates of marriage of the earliest ancestors married in the same region as their descendants were used to measure the age of individual ancestral roots. The average regional ages vary between 16 and 157 years, while some individual roots reach as far back as 300 years in the same region. The proposed method can be useful for assessing how deeply rooted a contemporary population is at a local, regional, or other geographical level.

摘要

这项研究提出了一种新的方法来衡量人口中祖先的深度。这种方法揭示了导致当今人口在整个空间分布的迁徙运动。该方法应用于来自魁北克省（加拿大）的17个地区的5,100个家谱的数据集。在与其祖传人相同地区结婚的最早祖先的结婚日期用于衡量各个祖先的年龄。该地区的平均年龄在16至157岁之间，而同一地区的某些个体根源可以追溯到300年前。所提出的方法可用于评估当代人口在本地，区域或其他地理级别的扎根程度。
