Hi Sharon,
I have looked at this family over the last few days. I feel confident that the two profiles are the same man. I have noted that there appears to be a glaring mistake on the family tree which is on the LDS Family Search. with Elias' wife giving birth in her 60s. The is a generation missing I think.
I also noted that there are other ways to spell the Surname, having " i " instead of the first " e " that is Linkinhoger. All the censuses seem to show the same people with different Surname spellings. ugh.
The newspaper articles show a lovely family celebrating a debutantes ball and identified a number of relatives. Unfortunately my old computer has karked it, and this is where I had put this information. I found 'Find my past', very good for locating your family.
If you can get more information for Elias in the Civil War I believe you may be able to fill in that generation gap. I don't know too much about accessing those files, as most of my research is located in Australia. I Would say I would look up more of your family but I will be on holidays for a few weeks Hope this is helpful Cheers
