Lelia P. Roby (née, Foster; pen name, Miles Standish; December 25, 1848 – September 18, 1910) was an American philanthropist of the long nineteenth century.

[1] On June 12, 1886, in Chicago, Illinois, where she lived, she founded the order of the Ladies of the Grand Army of the Republic, which started with 25 members, and by 1893, numbered about 15,000 mothers, wives, sisters and daughters of soldiers and sailors who served in the civil war of 1861–65.

The members of that order pledged to assist the Grand Army of the Republic in works of charity, to extend needful aid to members in sickness and distress, to aid sick soldiers, sailors and marines, to look after soldiers' orphan's homes, to see that the children obtained proper situations when they left the homes, to watch the schools, and see to it that the children received proper education in the history of the country and in patriotism.

It was passed, for a large majority of the legislators were old soldiers, and the fact that Roby was their friend made voting for a measure she advocated an acceptable duty.

She also served as president, South Side Study Club of Chicago; and vice-president, Woman's National Press Association of Washington for Illinois.
