McKibbens/McKibbins in Co. Down

I am looking to connect with any present day McKibbens (McKibbins)  in Co. Down.  "My" McKibbens were from Co. Dublin, but the last known relatives died in 1970.  What I know follows:

Alexander McKibben, b. unknown, d. 4/7/1896 - married to Anne ?.  They are listed on their son Alex's headstone in Holmpatrick Cemetery, Skerries, Co. Dublin.  Their children were Alex McKibben (b. 1841, d.5/13/1910, buried in Holmpatrick Cemetery; Francis McKibben b. 1844, Robert McKibben b. 1846, Anne McKibben b. 1848, Elizabeth Mary McKibben b. 1850, George McKibben b. 1858, and Mary Jane McKibben (my great-great grandmother) - baptized in Balcunnin on 5/15/1853; d. 11/9/1880 in San Francisco, California, USA - married Sylvester Moore of Balbriggan, Co. Dublin, in San Francisco on 2/17/1874.

Mary Jane's brother Alex married a Jane Scott Andrews in Kilkeel, Co. Down.  Their children were Alexander G. McKibben (died in Canada), Robert McKibben, Jane "Jean" Scott McKibben - died in 1970 in the McKibben house/farm in Skerries, Samuel James McKibben - died in Florida, USA, James Nelson McKibben - also died in 1970 on the Skerries farm, Charles Gordon McKibben - died 10/30/1917 in France during WWI, and Francis Rudolph McKibben d. 1921.

I would love to find any present relatives to learn more about the McKibben family history.

Thank you,

Susan
