Thank you both for replying. I don't believe I asked the question correctly.
I have two couples, John Foley/Ellen Cavanagh and Michael Malone/Anna McNamara. I believe both couples remained in Ireland but their children emigrated to the U.S., both ended up in LaSalle, Illinois. Elizabeth Malone married Michael Farrell at St Pat's in LaSalle in 1851. The parish register listed his parents AND her parents (the above Malone/McNamara). Michael Farrell died between 1855-1857. Edward Foley married Elizabeth Malone Farrell in 1857 at the same church (St. Pat's) and his parents were listed (the above Foley/Cavanagh).
I've searched through numerous Irish parishes looking for baptisms of Edward Foley and Elizabeth Malone. Mostly Edward Foley but occasionally would run across a Malone baptism in the same parish. I've been mostly unsuccessful. Edward was born between 1822-30 and Elizabeth almost assuredly about 1830.
My thinking is, maybe looking for death records in Ireland would produce some results. If both parents stayed in Ireland AND survived the famine, would death records record the name of the spouse? Assuming life expectancy of 50 years and both sets of parents were born 1790-1810, we'd be looking for death records from 1840-1860. So, would a death record of John Foley list his spouse? Or would a death record of Ellen Foley list her spouse or her maiden name? The same question for Michael Malone, would his spouse be listed in a death record? Same question for Anna Malone, would her spouse be named or her maiden name recorded? I suppose it's possible both parents died before, during or after the famine years. Maybe the reason the children emigrated?
I'm relatively confident Elizabeth emigrated in 1847 with her two sisters, Margaret and Susan. All three are listed on the ship Brooksby, ages 17, 19 and 18, respectively. The parish register with Edward and Elizabeth's marriage lists one of the witnesses as Margaret Malone. The 1900 U.S. census has Elizabeth with an immigration year of 1847. Edward lived in Pennsylvania for a number of years and the 1850 census has him, aged 28. He applied for citizenship in Schuylkill Haven, PA in 1852. In 1860 he became a citizen and that document, in Illinois, lists Schuylkill Haven, PA. The 1860 census lists both he and Elizabeth as 30. He died in 1863 and the St Pat's parish register reads, "I buried Edward Foley, aged about 40". That's why I have his birth between 1822-1830. Elizabeth had a son and two daughters with Farrell before he died and two daughters and two sons with Edward Foley before he died. She lived to the ripe old age of 90 or so. Her obituary from 1919, said she was in her 90th year. She outlived all but two daughters from Farrell and her youngest son Edward. Her first son with Foley was John. He is my ggrandfather.
So, a mysterious John Foley/Ellen Cavanagh had at least one son, Edward, who emigrated to the U.S. and married an Elizabeth Malone Farrell also with mysterious parents, Michael Malone/Anna McNamara. Their oldest son John married a Julia Travers in LaSalle and had five children. The oldest was Edward and he is my grandfather.
If there is any more information you need, let me know. I'd just like to know if searching for/finding death records in Ireland is a worthwhile project for me?
Thanks again.
