Margaret Elizabeth Tierney (14 Jan 1860 - BEF 1942)

The proposed relationship of Margaret Elizabeth Tierney as the mother of James Joseph Tierney Curran, Edwin Russell Curran MD and Eunice Eleanor Curran Carmody(Twin) is supported by DNA evidence indicating shared ancestry within the family lines.

Specifically, DNA evidence confirms a distant cousin relationship between GSGHH (a descendant of the Edwin Russell Curran MD ancestral line) and PCD (a descendant of the James Joseph Tierney Curran ancestral line) with a shared segment of 179.83 cM across 6 HIR segments.

It also confirms a 1st cousin, twice removed relationship between PCD (a descendant of the James Joseph Tierney Curran ancestral line) and SL (a descendant of the Eunice Eleanor Curran Carmody(Twin) ancestral line) with a shared segment of 209.79 cM across 9 HIR segments.

These matches are consistent with their placement within these shared ancestral branches.
