I am searching for William McKiv(e)tt and family, could be McKiv(i)tt, or even McK(e)vitt) born in Ireland, possibly Warrenpoint, around 1829. I have his son Patrick McKivett’s marriage cert to Mary Ann Mathews in 1889 in England. From census details both were born in Ireland. This was a catholic marriage. Mary Ann's father was John Mathews. Any help with this family in Co Down would be greatly appreciated. Thank you very much.
