During internal struggle within Carlism he sided with the progressist faction against the traditionalist one and helped to tip the balance in favor of Prince Carlos Hugo.

The paternal line was traditionally related to military; his great-grandfather Ignacio Romero Cepeda owned large estates near Osuna,[2] held high posts in Spanish possessions in America, was made Marqués de Marchelina in 1858[3] and served in the Senate in the early 1860s.

[29] Either in 1930 or in early 1931 he was transferred to Madrid, where as teniente he served at unspecified position in Fábrica Nacional de Productos Químicos,[30] an army establishment engaged also in development of chemical weapons.

[32] In terms of political preferences the Romero family has been traditionally related to conservatism, the great-grandfather and paternal uncle serving as senators respectively in the 1860s and 1910s.

None of the sources consulted provides any information on early political engagements of Ignacio, though as member of Maestranza de Sevilla he was linked to mainstream right-wing monarchism.

[33] In early 1933 the Andalusian party leader Manuel Fal Conde nominated him vice-president of Centro Tradicionalista de Sevilla and treasurer – i.e. the third in line of command - of the Seville Junta Provincial.

[34] Following wedding Romero left Spain for a long honeymoon trip abroad,[35] but later resumed party activities and acted among leaders of the Seville requeté organisation.

[38] In the evening of July 18, 1936 Romero took part in requeté assault on the Gobierno Civil premises in Seville,[39] which contributed to swift seizure of the city center.

[42] Following re-organization of Carlist troops he assumed command of machine-gun company, in the first half of 1937 deployed in the Jaén province;[43] he was one of few professional officers in so-called Tercio Virgen de los Reyes.

In late March 1938, during fierce combat for position named Mano de Hierro, Romero was heavily wounded by exploding shrapnel;[47] he escaped death but had his leg amputated.

[48] In late March 1938 Romero was nominated to Comisión Gestora del Ayuntamiento de Sevilla, the body which consisted of members appointed by the administration and which served as temporary replacement for the normally elected city council.

Reportedly he also demanded that incarcerated ex-Republican officers like Urbano Orad de la Torre are not held in atrocious, barbaric prison conditions.

[58] He cultivated olives and operated an own oil-mill, integrated within structures of the oil and vinegar holding, Compañía Internacional de Maquinaria Aceitera.

[59] Following a period of total absence in the press, in the early 1950s Romero re-appeared in local Andalusian titles, though on societé column only.

[60] He was mentioned either as member of Real Maestranza de Sevilla[61] when attending related events[62] or during family gatherings, especially that in the late 1950s his older children were already getting married and wedding ceremonies turned into aristocratic Andalusian congregations.

As such, he was bombarded with alarmist notes from the rank-and-file and local structures; they complained about alleged left-wing turn and betrayal of orthodox Carlist principles.

[75] In 1968 carlo-huguistas removed José María Valiente from position of Jefe Delegado and replaced him with a collegial executive, Junta Suprema; Romero was nominated as one of its members.

[80] Romero was nominated jefe of Partido Carlista in the Seville province[81] and the claimant hailed him as “el lealísimo marqués de Marchelina”.
