Kathy FitzGerald DNA matches

Kathy FitzGerald has DNA matches to my family.
But it is unclear what they mean.

DNA match to my family

Kathy FitzGerald is a DNA match to people in the Cashel family, namely me and James Riordan and Madeline Conacher.
The match to me and James Riordan is through the same DNA segment, on Chromosome 4. So the match must be through the Blennerhassett Cashel line.
To do: Check chromosome for the Madeline Conacher match.

How are we related? Her ancestry has many Anglo-Irish Munster families. But I cannot see any line by which we could be related except through the Blennerhassett and (maybe) Fitzgerald lines.
We have two theories of our own Blennerhassett descent:

• The Letitia theory (pretty much definitely false) would give Kathy FitzGerald and us common ancestors Capt. Edward Fitzgerald (born maybe c.1675) and John Blennerhassett, "Black Jack" (born 1665). Too early to have DNA showing up.

• The Baronets theory (largely proved now) would give Kathy FitzGerald and us common ancestor Capt. Robert Blennerhassett (born est c.1622). Also too early to have DNA showing up.

Neither theory seems likely. Probably the match is through another recent line we do not know about.

DNA match to Eileen Owen

Kathy FitzGerald is a strong DNA match to Eileen Owen.
This is in fact explained by the fact that they both descend from the Gentleman family in the early 19th century. The common ancestors are Robert Gentleman and his wife Margaret Goodman.

• Eileen Owen also descends through Yeilding from Eagar. Her common ancestors with Kathy FitzGerald are Alexander Eagar and Triphena Browne in early 1700s, rather far back.
• Eileen Owen also descends from Blennerhassett. The common ancestor is Capt. Robert Blennerhassett (born est c.1622). Again, this seems too far back.

DNA match to Vincent Butler

Kathy FitzGerald is a DNA match to Vincent Butler.
While he descends from Anglo-Irish Munster families linked to Blennerhassett, he does not descend directly from Blennerhassett. His match with Kathy FitzGerald is unexplained.
This may be key to how Kathy FitzGerald matches our family. Maybe she has a recent Yielding ancestor?
