I believe I have some information that might be helpful to you. My grandfather, Joseph Franklin Yax was married three times. His second wife was a Laura Ward. Some of his family descendents went to Michigan from NY. I know that if this is the Laura Yax you are asking about, they had 2 sets of twins, Nellie and Lillie, Effie and Elsie. Please e-mail me if this is helpful information, as we can exchange what we do know.
