Lasker 's coefficient of relationship by isonymy was used to analyse surname data taken from the 1851 Census returns for Fylingdales parish, North Yorkshire. At this time the population had a thriving maritime economy based on the coastal town of Robin Hood's Bay, as well as agricultural and some industrial activity inland at Thorpe , Raw and Stoupe Brow. There is a marked heterogeneity in the distribution of surnames within the parish, with both place and profession constraining isonymic relationships. Within-group kinship is high among the mariners , fishermen and shipowners of Robin Hood's Bay and Thorpe , and the relationship between these different maritime groups is also very high. Kinship is generally far lower both within and between the land-based occupational groups, and between these and the seafarers .
运用拉斯克同姓系数对取自北约克郡菲林代尔斯教区1851年人口普查记录中的姓氏数据进行分析。当时，该地区人口以沿海城镇罗宾汉湾繁荣的海洋经济为基础，同时在内陆的索普、罗和斯托普布罗也有农业和一些工业活动。教区内姓氏分布存在显著异质性，地点和职业都对同姓关系有所限制。罗宾汉湾和索普的水手、渔民及船主群体内部亲属关系紧密，这些不同海洋群体之间的关系也非常紧密。陆上职业群体内部及相互之间的亲属关系通常要低得多，与海员群体之间的亲属关系也是如此。
