Mumsie Jaya was one of Ma's favorite people - saying that she (Ma) was Daughter Number One (Mumsie has four daughters!). Originally from Trinidad by way of New York, Mumsie was a professional seamstress, making many of Ma's outfits over the years.
Sita and Ma went way back to the early days in New York, and both growing up Jewish they had a lot in common. This was perhaps the edge that allowed Sita the boon that no one else ever got, of being able to impersonate Ma at our holiday festivities! She was a natural comic (as was Ma), and would have us all howling with laughter.
