Wayne, you asked about Sarah J. Lewsader who died on May 24, 1913, in Covington at age 71 yrs.I'm wondering if she isn't the second wife of Thomas J., Sarah Jane Perrin.I see that Thomas remarries again in 1914.Sarah J. died in 1913. Their ages would be compatible too though that doesn't mean too much. Thomas J. was born in '38 and the Sarah J. who died in 1913 was born probably in '42 or '41.
Yes, the Mary J. Lusader who died at age 77 in 1901 could be an unmarried daughter of Andrew.The only Mary J. Lusader that I found was in the household of John Lewsader(brother to Isaac and hopefully son of Andrew) in the 1870census of Highland Twp, Vermillion Co. John is 50yrs. old now and his wife Sarah A. has died.I don't know if Mary J. is his second wife or possibly a step daughter. Regardless of her position in the family, she doesn't fit age-wise with the Mary J. who died in 1901.The Mary in John's household is listed as 31 in 1870. I don't think she will qualify for the Mary in question.
I do want to call your attention to a message posted by Ruth Czigan back on August 15, 2000. It was a reply to your message about Andrew.I'm going back to it to make my response, but I want your input.
