Another ONLNE POST: I am looking for John Burton Griffith he was born in Illinois 1854 . He had two sisters Sarah and Elizabeth and one brother Joseph. This family or I might say John and Elizabeth were in Nebraska in 1870. In 1873 Elizabeth married a David Bryan but what happen to John?.
Is there more information you can add about this family and their spouses and whereabouts? It could be Jonathan Burton Griffith dies with no death record available to us. It could be he is off on his own somewhere. But it COULD be that his siblings’ whereabouts may be a clue to his whereabouts. Thus, lacking other options, one good strategy would be to “follow the siblings.”
In this original post, we do hear of John Griffith’s full name, his date of birth, his parents and siblings, his whereabouts in various years as you know them, etc. are not given.
So maybe you have more clues to share? If so, that’s our next step. After that, maybe it's "follow the siblings"? It could be John Burton Griffith is lurking in the census but hard to find because of a transcription problem or whatever.
