Your grandfather, Henry Lee Lakin, was my uncle. Paul Lakin was my father. I've been researching this family and their ancestors for many years. I'm happy to share what I have. What you found through the LDS church was probably from my submissions. I haven't found anyone else researching this family. I'd love to connect.
FYI: Henry's mother was a strong and faith-filled woman. She died the year before I was born, but I have letters and cards she sent to my parents and brothers. I would have liked to have met her. There are many stories I can share with you. The family dealt with far more than their share of tragedies, yet all the letters from my father's parents and siblings are full of optimism and humor. They're fun to read.
Do you have any photos? I have only a couple of photos of Henry's siblings as adults. Nothing from childhood and none as group or family photos. I also have at least one small picture of his mother. Let me know what you'd like.
