“…Considering all of the dimensions examined, only a few documented family relationships were reflected in the cluster analysis; less than shown by non‐metric traits (Cvrček et al ., 2018). However, the closest pairs are again the closest relatives, such as father and son, mother and daughter, siblings, and grandparents and grandchildren.…”

“…(1987), Reichs (1993) and other authors (Kim et al ., 2013) allow the use of frontal sinus morphology for kinship analysis. We came to the same conclusion in our analysis of non‐metric traits on the same sample with known genealogical data (Cvrček et al ., 2018); that is, the greater the degree of biological relationship, the greater the degree of morphological similarity. However, we emphasize that the degree of morphological similarity of biologically related individuals based on the frontal sinuses is less than that using non‐metric traits (Cvrček et al ., 2018).…”

“…The skulls of 41 adult individuals (25 males and 16 females) aged 20–90 years with known genealogical data were available (Cvrček et al ., 2018).

“…The coefficient ( r ) was calculated using a tabular approach (Falconer and Mackay, 1996) based on the method of VanRaden (1992). Use of a logarithm (logR) eliminates entirely unrelated individuals (their coefficient of relationship is always zero; thus, the logarithm is not defined) and allows graphical expression of the relationship between the degree of similarity and the biological distance only for biologically related individuals (Cvrček et al ., 2018). We used a linear model to test the relationship between the DS of each dimension and the logarithm of the biological distance for all related pairs in the sample (level of significance α = 0.05).…”

Frontal sinus analysis has potential utility for detecting biologically related individuals. However, the methodological approach to its evaluation, as well as its informative value, have been questioned. The aim of this work is to introduce a new approach to evaluating the frontal sinus using the ‘external supraorbital line’ (ESOL) and to determine whether there are sex differences within families in frontal sinus measurements and whether frontal sinus similarity reflects known genetic relationships in both measurements and morphology. We examined the skeletal remains of 41 adult individuals (25 males, 16 females), all members of one family over four generations (19th to 20th centuries), including individuals with very close consanguinity. CT images of skulls were acquired, and both the dimensions and morphology of the frontal sinuses were analyzed using their portions above the ESOL. No significant sex differences were found within families based on frontal sinus dimensions. Significant relationships were found between biological distance and the maximum height and morphology of the frontal sinuses. The greatest degree of similarity was found among closely related individuals. Additionally, in several cases, there was a greater degree of similarity between first cousins or grandparents and their grandchildren than among siblings or parents and their children. Total surface, volume and width are not significant indicators of relatedness. Known genetic relationships are also supported by individual morphological features. Variability within families with very close consanguineous relationships was lower than within families with common degrees of consanguinity, although differences are significant only for some variables.

The evaluation of frontal sinus similarity is one way to detect biological relationships, especially in small groups, including families of historically known personalities. However, possibilities for studying this issue are currently limited. This contribution deals with the frontal sinuses of a rare osteological sample with known genealogical data, members of the noble Swéerts‐Sporck family from the 17th to 20th centuries. The aim is to verify whether the frontal sinuses reflect documented family relationships. Basic dimensions of the frontal sinus such as total surface area and volume, and maximum height and width, and also morphology and anatomical features were evaluated using computed tomography scans. The portions of the frontal sinus above the “external supraorbital line” were analyzed. The degree of similarity between biologically related individuals was determined for each variable and compared with their known biological distance. The degree of similarity based on dimensions was evaluated using both the unadjusted measured data and standardized data adjusted to size. For the unadjusted dimensions, a positive correlation between morphological similarity and biological relatedness was apparent. On the other hand, no positive correlation was apparent for most of the standardized data. Only total volume showed a very weak indication of a positive trend in the standardized data, but this was weaker than in the original values. A positive quantifiable relationship between morphological patterns and biological distance is not clearly indicated. However, nonmetric features do support the documented relationships of the individuals.
