Margaret (Shea) Sullivan Lyne (JJM's maternal grandmother)

Also known as: Margaret Shea, Margaret Sullivan, Margaret Lyne, Margaret Shea alias Sullivan

family confidence: 95 — certain (corroborated)

JJM's maternal grandmother. Born Shea (date unknown, probably 1820s-1830s Eyeries area Co. Cork). Married twice: 1. **John Sullivan**, 20 Feb 1855 Eyeries (her first marriage; he died before 1865) 2. **Myles Lyne**, 9 June 1865 Kilcatherine RC Chapel of Eyries (her second marriage) Per the 1865 marriage cert, she's identified as "Margaret Shea alias Sullivan" (i.e., previously married name Sullivan, birth surname Shea). Children: - From John Sullivan marriage (1855-1865): UNKNOWN — any Sullivan children Margaret had with John have not been identified in the archive. An earlier speculative identification linking Patrick "Tailor" Sullivan (m. Catherine Murphy 1884) as Margaret's son was REJECTED by the user 2026-05-27 — Patrick Tailor is from a different Sullivan line. - From Myles Lyne marriage (1865+): Ellen Lyne (b. ~1863 per 1900 US census — but if Margaret didn't marry Myles until 1865, Ellen's 1863 birth date must be off; could be that Ellen was b. ~1866-1870 after the second marriage; the 1900 census age 36 + Sept 1863 birth- year reading may be unreliable). **User confirmed 2026-05-27: Margaret is Ellen's biological mother**, ratifying the biological-from-1865+-marriage reading and rejecting any stepmother-via-first-marriage interpretation. Locking down the date tension (1865 marriage vs the c.1861-63 census birth-year reading) is the open thread to resolve — most likely the census age is what's wrong.
