I think this family might have been related to a Cherry family who ended up in Scotland, in the village of Thornliebank, parish of Eastwood, in Renfrewshire. I only know about them because I had Petticrew ancestors from Belfast who came over to Scotland in the 1830s and settled in Hawick. In the 1861 census Daniel Petticrew - brother of my ancestor Agnes - wasn't at home in Hawick and I eventually found him living with a family called Cherry in Eastwood, and described as "visitor". I discovered that the father/husband of the family, Hugh Cherry, master shoemaker, had recently died and maybe Daniel had known him or even been related and had gone to Eastwood for the funeral.
Hugh's death-certificate states that he was 50 and the son of Moses Cherry, farmer, and Ann Hamilton. He was married to Elizabeth Murray and in 1861 their children were Ann, Grace, Elizabeth, Moses and Margaret.
Ros Davies's surnames of Co. Down site has an entry for Hugh Cherry and Elizabeth Murray, who were married in 1836 at Killinchy. Daniel Petticrew's mother was a Jane Murray and his wife was Abigail Hamilton.
