Eva Mackin was my great grandmother, she had infact 6 children. Stanley, Douglas, Ronald, Jean, Joyce & Betty. Stanley died in 2009 in jersey, Douglas in 1999 in portsmouth, Ronald in 1941 on HMS hood, and the 3 daughers are all still alive. Jean lives in Jersey and Joyce and Betty in england. A possible reason why you are finding hard to find people is because half of the family spell the name MACKIN and the the half MAKIN . Due to drunk registars miss-spelling over the years so my grandfather told me. Any more info please contact me i have plenty more to share..
