The maternal relationship between Edith Cora Swartzlander and her son
Richard D. Streeter is confirmed by the direct inheritance path of autosomal DNA down to their DNA tested descendant KV.
The segmental (via DNA segment triangulation) and total DNA shared between KV and other confirmed descendants of
John Francis Delong/
Sarah Winteringer is consistent with the expected ranges for their respective relationships. Since KV descends from John Francis Delong/Sarah Winteringer through Edith Cora Swartzlander and her son Richard D. Streeter, the presence of significant shared DNA between KV and other known descendants of John Francis Delong/Sarah Winteringer validates the generational links along this maternal line.
This supports the conclusion that DNA was passed from MRCA couple John Francis Delong/Sarah Winteringer through Edith Cora Swartzlander to Richard D. Streeter, and ultimately to KV, confirming this direct ancestral connection through multiple generations.
