Looking for any information on my Lunny ancestors. What I know of names is below.

My great-grandmother is GERTRUDE LUNNY (b.1893 - d.1919 in SF). She married Edmund DeMARTINI and had two(2) children, Walter and Veronica. She had five (5) siblings: Mary, Irene, Anita, Joseph, and Veronica.

Her father was EDWARD JOSEPH LUNNY (b.1866, Indiana - d.1920, SF). He married Elizabeth MORAN and had 6 children (listed above).

His father was BERNARD LUNNY (b.1833, Ireland - d.1911, SF). He married Elizabeth GRUME(GROOME) and had eleven (11) children: Mary, Catherine, Edward (above), William, Hugh, Ellen, Anne, John, Eliza, Thomas, and Margaret.
---I am not possitive of the children after Edward.

[not possitive on the following]

His father was probably JOHN LUNNY (b. abt. 1800, Ireland - d. ???? in USA maybe). He married ANN ????. Children may include Bernard (above), Mary, Elizabeth, and potentially others.

COUNTY CORK, IRELAND is a remembered by my grandmother as being a locale of the my Lunny ancestors. Any information would be greatly appreciated.

Thank you.
