Jenelle isn't the only Evans with a troubled past...
What about Ashleigh?

Then, there is Jenelle’s older sister, Ashleigh — a mother of two and a Hooters waitress. There’s a lot more information on her, but it’s equally difficult to verify. Despite rarely appearing on MTV, Ashleigh has actually come into the Teen Mom narrative quite a few times over the years, but it’s hard to say what’s true and what isn’t.
Ashleigh has a reputation for lying about her life and family (like when she admitted to lying about being abused by an ex-husband), so most of what we know about her is disputed.
Just Sister Stuff…

See, Ashleigh and Jenelle are on bad terms to say the least. According to Evans, Ashleigh is the reason that she kept her most recent pregnancy a secret for as long as she did. When Barbara confronted Jenelle about her secrecy after news of the pregnancy came out, the star explained that she didn’t want to tell Barbara for fear that Ashleigh would sell the story to tabloids for her own gain.

Aside from that, Ashleigh has two children of her own. She’s got a well-documented (but disputed) history of health problems. She and Jenelle have had an ongoing and public feud for many years now, with Jenelle always asserting that Ashleigh is “jealous” of her.
And she might be on to something…
