• Ada's mother, Anne, who also possessed a fancy nickname -- the "Princess of Parallelograms" -- taught her math and science at a very young age. This was rare, as it was a time when women weren't supposed to be concerned with such matters. Oddly, this was done primarily as a preventative method for insanity, which she feared Ada might have inherited from her father, whom she loathed.*

Wikipedia Biographical Summary:

"...Anne Isabella Noel Byron, 11th Baroness Wentworth and Baroness Byron (17 May 1792 – 16 May 1860) was the wife of the poet Lord Byron, and mother of Ada Lovelace, the patron and co-worker of mathematician Charles Babbage..."

"...Her names were unusually complex. She was born at Elemore Hall, Pittington, Durham as Anne Isabella Milbanke, the only child of Sir Ralph Milbanke, 6th Baronet, and his wife the Hon. Lady [Judith] Milbanke, sister of Thomas Noel, Lord Wentworth.[1] When Lord Wentworth died, a few months after Anne Isabella's marriage to Lord Byron, her father, who inherited a large part of the estate, changed his name to Sir Ralph Noel. When her mother died, Anne Isabella and her husband changed their names to Noel also; her mother had required this as a condition for inheriting her considerable estate; her mother disliked Byron's name so much that she had written a letter to the Prince Regent, requesting that he give her daughter the title of "Lady Wentworth" (a barony separate from the one she would eventually inherit), so that her parents would not have to call her "Byron".

So she was first Anne Isabella, Baroness Byron or Lady Byron, and then Anne Isabella Noel, Baroness Byron. Her uncle had been both Viscount and Baron Wentworth, which titles were inherited differently: the viscountcy became extinct, and the barony fell into abeyance between her mother and her cousin Nathaniel Curzon, 3rd Baron Scarsdale. When Curzon died without heirs in 1856, Baroness Byron became Baroness Wentworth, in her own right, as sole claimant; but she did not use the title. She signed her letters "A. I. Noel Byron" and her will as "Baroness Noel-Byron". The world knew her as "Lady Byron", and her friends called her by her nickname "Annabella"..."

".... Often described as cold and prim, she seemed an unlikely match for the man who would become her ultimate obsession, the dramatically dark and "morally fractured" poet Lord Byron. Their first meeting occurred in March 1812..."

"...When Lord Byron proposed a second time to Miss Milbanke in September 1814, she accepted. The couple were married privately, and by special licence, at Seaham Hall in County Durham on January 2, 1815..."

"...In the late stages of pregnancy, she feared Byron might have been going mad. In November 1815, she wrote to Leigh and told her of Byron's moods and behavior. In answer to her sister-in-law's letter, Leigh traveled to the Byrons' home to assist. Upon her arrival, she became the subject of Byron's wrath and believed him to be temporarily insane. On December 10, Lady Byron gave birth to the couple's only child, a daughter whom they named Ada. Byron's despair seemed to increase..."

"...Lady Byron died of breast cancer on May 16, 1860, the day before her 68th birthday. She was buried in Kensal Green Cemetery at Kensal Green in London..."
