Thankyou so much for helping me

some of the research is so difficult. I dont want to take too much of your time but the last few names I am a little confused by as I havent come across them yet. Were they buried together? Also the daniel kervin's is utterly mind boggling lol he just seems to dissapear off the census records but Ann is still classed as his wife and not widow. The 1881 census is the last and only I have him on at age 40.. some of them don't half make it difficult lol..
thankyou so much again, I really appreciate it xxxx
