Didn't see any Mercedes parked on list!! 
That's what makes this hobby so enjoyable, being able to have a wee laugh along the way when all our concentration is buried in names/dates/places/banging our heads off desks/walls...it's great to have some amusing quips to lighten things

To Cogs (Be prepared)!...
Did you ever know any of your mother's siblings?
Do you know if she kept in touch with any of her siblings?
Do you recall her mentioning anything which may not seem significant but could be (anything regarding her family at all)?
Do you recall any other surnames mentioned or places?
Did your mother
never mention her family or parents?
I actually gleaned a lot of 'vague' info, from my aunt (my mother's sis) on their parents when I started asking questions (my mother died 1982) as things came to her mind which she didn't think to be of any use but I used every thread she gave me & from knowing nothing (they were orphaned) those little 'threads' were the making of my maternal line now back to 1700s!
If you recall anything at all it is worth mentioning no matter how vague!
