Gerrard, Archibald Wester. Ireland

On an old family tree I have Archibald Wester Gerrard married Jane Price. Jane was the daughter of William Price of Annsborough Co Kildare Ireland and it seems she was born in the 1850s. They had three children. William Gerrard married Marie; John Gerrard married Lena and Margaret Gerrard married John Gruner (a German) and had four children: Frederick, Justin, Alexandra and Margaret. That’s all I have. No dates. Any clues?
