Kaspar Anton Karl van Beethoven was born in 1774.
Maria Margaretha Josepha was one of Ludwig van Beethoven's sisters who died in infancy (in total 4 of his siblings died soon after birth). His brother Carl and Johann were his only surviving siblings.
His Brothers were: Caspar Anton Karl (born in April 1774) Nikkolaus Johann (born in October 1776) Franz Georg (baptizes on 1781, died 2 years later) Sisters: Anna Maria Franziska (baptized on 1774, died 4 years later) Maria Margaretha (baptized 1786, died 1 year later) and his older sister: Ludwig Maria(born on 1769 in august, who live for six days) So it was Caspar Anton Karl and Nikkolaus Johann who survived
Beethoven had a grandfather, also named Ludwig who died when he was very young. He had a grandmother named Josepha who passed on her alcoholism to her son, Beethoven's father, Johann. Johann was a highly irresponsible father who had to be looked after by his children more than he looked after them. Beethoven's mother, Maria Magdelena died when Beethoven was 17 but was a wonderfully kind woman who Beethoven loved very much. Beethoven older brother, Ludwig Maria died before Beethoven was born. Beethoven had two younger brothers named Caspar Anton Carl and Nikolas Johann. He had more younger siblings but none of them lived to adulthood. Their names were Franz Georg, Anna Franziska and Maria Magaretha. When he was older Beethoven had a nephew (son of Caspar Carl) named Karl who he looked after once Caspar Carl had died. It was over this boy that Beethoven had a bitter custody battle with Johanna van Beethoven (Caspar Carl's widow). Beethoven never married but he had some illegitamate children named Minoa (with Josephine von Brunswick and Karl with Antoine Brentano and possible others as well.
Beethoven's mother, Maria Magdalena, gave birth to Ludwig Maria in 1769 but she died 6 years later. Beethoven was born in 1770. Later Maria gave birth to 5 other children but only 2 survived, Caspar Anton Carl and Nikolaus Johann. So in the end, Beethoven had 2 siblings, who he took care of for 5 years of their life :)
