I am one of the 'fortunate' ones as I have been able to find loads of press coverage about my ancestors. My ancestors appear to have been of the colourful type - there are stories of law breaking, drunkeness, tragedies, war deaths, you name it - there was even a murder trial with my Great x 2 ancestors as the accused in the 1850s.
Thankfully, they were acquitted as I believe they were innocent. There are some more positive articles too.
However, although on a positive I have many interesting articles to read - the downside is I believe my ancestors had more than a fair share of suffering, angst and drama in their lives. If I could wave a magic wand and change things for the better for them I would even if this would mean losing all these colourful stories.
I think you have been given a lot of good advice on here. You could also try putting in just 'Mr' or 'Mrs' so and so. For example, a couple of ancestors of mine were referred to as 'Mr Senior' and 'Mrs Young'. Other things mentioned in articles such as the address assured me that these are my ancestors.
Or you could try just putting on an initial and a surname or reversing this to find a war mention.
I would also look for mistakes in spelling of names. For example, if your ancestor is called Watson they may have accidentally appeared with a spelling error such as being called Witson or Wetson. I have known this to happen. Other things mentioned in write ups may be able to clarify if they are person you are looking for.
If you know the address try just putting in just that in search box. I did that and I discovered a great x 2 Grandfather who appears to have given himself a completely different first name for a while - he was called Philip but was going under the name of Ralph which was his wife's Father's name. I know for definite this is him because of the address and other things referred to in articles. I have another ancestor who went by an alias. In my research I have found that other people sometimes used an alias too . My ancestor James Conroy was also known as Gilroy (according to a newspaper report) and I also found one record where he appears as Kilroy! I do not know if this was by accident or design. His wife was Elizabeth but in an odd newspaper she was referred to as Bessie and Betty.
I have a brother of a bloodline ancestor who had a nasty boiler explosion in the late 19th century which unfortunately killed his housekeeper. Most newspapers spell his name correctly as Richard but one refers to him mistakenly as Robert.
So to sum up - try researching for known addresses, name changes, possible errors in print, etc.
Good luck with your searching!
Added: I sometimes wonder how my ancestors can be my ancestors as some of them do seem a bit wild. I, on the other hand tend to go a bit wild only when I am playing monopoly.
I wonder if I was a Founding and I have just never been told. Or perhaps my ancestors may have been able to lead much more calmer lives if they had been able to spend as much time as I do in archives, libraries and on RootsChat. Oh well, I suppose this keeps me out of mischief.
